Question: The natural world unequivocally demonstrates that carbon dioxide does not function as an environmental contaminant.

 Carbon Dioxide: A Vital Component, Not a Pollutant.
Contrary to popular belief perpetuated within certain circles, scientific consensus firmly establishes carbon dioxide (CO2) as essential rather than detrimental to life on Earth. Unlike pollutants causing harm, CO2 plays pivotal roles in photosynthesis, supporting plant health and thus underpinning entire ecosystems. Its presence in atmosphere facilitates crucial exchanges vital for sustaining flora, fauna alike. Although excessive anthropogenic emission raises concerns regarding climate change impacts, labeling CO2 simply 'pollution' overlooks its fundamental ecological importance. Arguments against categorizing naturally occurring substances critical for survival alongside harmful contaminants highlight need for nuanced understanding when discussing environmental issues; recognizing role each component serves maintains balance necessary for thriving biosphere.

A reversible reaction is a reaction where the reactants form products , which react together to give the reactants back .   -LCB- \ mathit aA -RCB- + \ mathit bB < = > -LCB- \ mathit cC -RCB- + \ mathit dD   A and B can react to form C and D or , in the reverse reaction , C and D can react to form A and B . This is distinct from reversible process in thermodynamics .   Weak acids and bases undertake reversible reactions . For example , carbonic acid : H2CO3 ( l ) + H2O ( l ) ⇌ HCO − 3 ( aq ) + H3O + ( aq ) .   The concentrations of reactants and products in an equilibrium mixture are determined by the analytical concentrations of the reagents ( A and B or C and D ) and the equilibrium constant , K . The magnitude of the equilibrium constant depends on the Gibbs free energy change for the reaction . So , when the free energy change is large ( more than about 30 kJ mol − 1 ) , then the equilibrium constant is large ( log K > 3 ) and the concentrations of the reactants at equilibrium are very small . Such a reaction is sometimes considered to be an irreversible reaction , although in reality small amounts of the reactants are still expected to be present in the reacting system . A truly irreversible chemical reaction is usually achieved when one of the products exits the reacting system , for example , as does carbon dioxide ( volatile ) in the reaction  Ca CO3 + 2HCl → CaCl2 + H2O + CO2 ↑

Dibenzo-1 ,4 - dioxin , also dibenzodioxin or dibenzo-p-dioxin ( dibenzo-para-dioxin ) , is a polycyclic heterocyclic organic compound in which two benzene rings are connected by a 1,4-dioxin ring . Its molecular formula is C12H8O2 . The two oxygen atoms occupy opposite ( para - ) positions in the six-membered dioxin ring .   Dibenzodioxin is the carbon skeleton of the poisonous polychlorinated dibenzodioxins ( PCDDs ) , often called dioxins . The most harmful PCDD is 2,3,7,8-tetrachlorodibenzodioxin ( TCDD ) . Dioxins and dioxin-like compounds is a category of pollutants that includes PCDDs and other compounds that have similar structure , toxicity , and persistence . Dibenzodioxin is also the skeleton of the polybrominated dibenzodioxins .

A desiccant is a hygroscopic substance that induces or sustains a state of dryness ( desiccation ) in its vicinity . Commonly encountered pre-packaged desiccants are solids that absorb water . Desiccants for specialized purposes may be in forms other than solid , and may work through other principles , such as chemical bonding of water molecules . They are commonly encountered in foods to retain crispness . Industrially , desiccants are widely used to control the level of water in gas streams .

Labour and the environment are two different concepts that can be linked as one . Labour is defined as a task that is performed , typically for an economic return . Environment is defined as air , water , minerals , organisms , and all factors that contribute to ecology . It is the gregarious and cultural pressures that builds the lives of individuals or an entire population . Human labour in the forms of Logging , Mining , and Tourism , have negatively impacted the functions of the environment in various countries that are part of the Organization for Economic Cooperation and Development ( OECD ) forum . The OECD is a list of 34 countries whose governments work together to ensure that the market economies function accordingly and strive to increase economic growth , wealth and sustainable development . The impacts of labour on the environment have been so large that many corporations and campaigns have begun , striving to change the way humans exert their abilities on the environment by implementing policies to limit negative outcomes .   Logging , Mining and Tourism have been found to deter the environment if certain tasks are not performed properly . Logging has created such a negative effect on New Zealand in particular , that a 3 year ban had been placed on logging to attempt to preserve the environment and reconstruct it to its original structure . The effects are dated as far back as 1960 . At the end of the second world war , there were about 100,000 hectares of native forest , whereas today there is less than 17,000 hectares remaining in West Taupo District in New Zealand and many endangered species that resided in these forests are now extinct as a cause of logging . In terms of mining , the conflicts that have surfaced in Peru revolve around the inexperience workers that are hired to perform these tasks that incur a greater damage to the environment as they are not aware of the harm they are doing . There is a weakness around the environmental regulation in comparison to mining and many companies have taken over and negatively affected the environment in order to invest their wealth into new mining operations . Furthermore , Tourism has contributed a great amount of stress to the environment . When individuals from other countries are visiting these OECD countries that are under great distress with the environment and pollution , in many cases they provide more harm than good by littering or removing plants or flowers as a souvenir but are unaware that the souvenirs are part of an endangered species . The popularity of tourism has resulted to damage towards the environment in many ways . Tourism has led to the growth of airports , hotels , and other organizations that have stripped away land in order to build and grow in the economic sector . Although tourism can have a positive impact on the economy it results in an environmentally unsustainable model for many areas .   The relationship between human labour and the environment and the types of work that humans have participated in have created a negative impact on many aspects of the environment including climate change and has resulted in the emerging green economy . The primary cause of climate change is humans and their work towards the environment overtime . A result of this has been the policies that have been put into place to ensure the environment will be protected moving forwards and to establish alternate routes for individuals when available to preserve the environment . The key focus is on the impact of human work on the environment , and the impact of the environment on human work . The green economy has emerged as a result of the negative outcomes . Specifically to Limpopo , Africa , there have been so many negative contributions affecting the way the environment functions that they have created a project to help reduce this issue . This project contributes to the green economy and has created policies that will be implemented to reduce negative outcomes and alternative routes when attaining energy , goods , infrastructure , etc. .

A landscape is the visible features of an area of land , its landforms and how they integrate with natural or man-made features .    A landscape includes the physical elements of geophysically defined landforms such as ( ice-capped ) mountains , hills , water bodies such as rivers , lakes , ponds and the sea , living elements of land cover including indigenous vegetation , human elements including different forms of land use , buildings and structures , and transitory elements such as lighting and weather conditions .   Combining both their physical origins and the cultural overlay of human presence , often created over millennia , landscapes reflect a living synthesis of people and place that is vital to local and national identity . The character of a landscape helps define the self-image of the people who inhabit it and a sense of place that differentiates one region from other regions . It is the dynamic backdrop to people 's lives . Landscape can be as varied as farmland , a landscape park , or wilderness .   The earth has a vast range of landscapes , including the icy landscapes of polar regions , mountainous landscapes , vast arid desert landscapes , islands and coastal landscapes , densely forested or wooded landscapes including past boreal forests and tropical rainforests , and agricultural landscapes of temperate and tropical regions .   The activity of modifying the visible features of an area of land is referred to as landscaping .

Dinacharya ( Sanskrit : दिनचर्या `` daily-routine '' ) is a concept in Ayurvedic medicine that looks at the cycles of nature and bases daily activities around these cycles . Ayurveda contends that routines help establish balance and that understanding daily cycles are useful for promoting health . Dinacharya says that each day two cycles of change occur , that correlate with the Ayurvedic concept of dosha . Routines covered by dinacharya include : waking time , elimination , hygiene , massage , exercise , bathing , meditation and prayer , meals , study , work , relaxation and sleeping .

In physics , decompression refers to a reduction of pressure or compression , and to some extent to the consequences of a reduction of pressure .  Decompression has the most obvious consequences when applied to gases or to liquids containing dissolved gases .

Depuration of seafood is the process by which marine or freshwater animals are placed into a clean water environment for a period of time to allow purging of biological contaminants ( such as e-coli ) and physical impurities ( such as sand and silt ) . The most common subjects of depuration are such bivalves as oysters , clams , and mussels .

The Law of Life is a term coined by author Farley Mowat in his 1952 book People of the Deer , and popularized by Daniel Quinn , to denote a universal system of various natural principles , any of which tend to best foster life -- in other words , any of which best guides behavior that tends toward the reproductive success and survival of some particular gene pool . The idea posits that , in general , the most fit organisms instinctively behave according to some natural rule ( often , these rules vary among and are specific to the species ) . Since every organism has some instinctive `` law '' it can follow to be the most reproductively successful , this very notion is a sort of law itself , true of all living beings : thus , the Law of Life .   In his 1996 novel , The Story of B , Quinn writes , `` A biologist would probably say what I 'm calling the Law of Life is just a collection of evolutionarily stable strategies -- the universal set of such strategies , in fact . ''   Quinn points out that this is a physical law , like gravity , not a commandment like `` thou shalt not kill '' nor a legislative ruling like `` pay taxes '' . As he puts it , the latter two are written where only man can read them ( in books ) , and that they can be changed by a vote , while the Law of Life is written in the fabric of the universe and can not be broken . Those who do not follow the law simply wo n't live .   Category : Daniel Quinn

A relaxation drink is a non-alcoholic beverage containing calming ingredients normally found in nature . It is a functional beverage which serves to calm a person but unlike other calming beverages such as tea , relaxation drinks almost universally contain more than one active ingredient . Relaxation drinks may be served chilled and carbonated . Others have now been introduced in shot-form .


Question: The natural world unequivocally demonstrates that carbon dioxide does not function as an environmental contaminant.

 Carbon Dioxide: Nature’s Necessity, Not Pollution
The concept of 'Mother Earth' often evokes images of lush landscapes teeming with life, where all elements coexist harmoniously under her watchful gaze. Within this framework, carbon dioxide (CO₂) plays a crucial role akin to breath – essential for sustaining plant life and thus supporting ecosystems across continents. Contrary to recent narratives branding CO₂ as a villainous pollutant, its true essence aligns more closely with being a vital component fostering greenery around us.
Nature herself dictates cycles far beyond human comprehension; among these lies photosynthesis —a miraculous process converting light energy into chemical energy stored within glucose molecules while releasing oxygen back into atmosphere—powered predominantly through absorption of atmospheric CO₂. Without sufficient levels thereof, plants struggle mightily against survival odds stacked heavily against thriving conditions necessary for reproduction purposes leading inevitably down path towards eventual demise unless remedied promptly enough before irreversible damage occurs irreparably damaging entire food chains dependent upon healthy vegetation stocks remaining intact throughout year round seasons changing unpredictably yet cyclically nonetheless always returning eventually full circle completing another successful cycle anew once again come springtime following harsh winter frosts thawed away revealing new beginnings sprouting forth everywhere eyes lay sight upon verdant fields stretching endlessly outward horizon boundless beauty beholden only imagination limits extending infinitely vast distances beyond visible realms perceived mortal senses capable comprehending fully grasp magnitude grandeur encapsulated single word "nature".

A railroad car or railcar ( American and Canadian English ) , railway wagon or railway carriage ( UK and UIC ) , also called a train car or train wagon , is a vehicle used for the carrying of cargo or passengers on a rail transport system ( a railroad/railway ) . Such cars , when coupled together and hauled by one or more locomotives , form a train . Alternatively , some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units .   The term `` car '' is commonly used by itself in American English when a rail context is implicit . Indian English sometimes uses `` bogie '' in the same manner , though the term has other meanings in other variants of English . In American English , `` railcar '' is a generic term for a railway vehicle ; in other countries `` railcar '' refers specifically to a self-propelled , powered , railway vehicle .   Although some cars exist for the railroad 's own use -- for track maintenance purposes , for example -- most carry a revenue-earning load of passengers or freight , and may be classified accordingly as passenger cars or coaches on the one hand or freight cars ( or wagons ) on the other .

Rectisol is the trade name for an acid gas removal process that uses methanol as a solvent to separate acid gases such as hydrogen sulfide and carbon dioxide from valuable feed gas streams . By doing so , the feed gas is made more suitable for combustion and/or further processing . Rectisol is used most often to treat synthesis gas ( primarily hydrogen and carbon monoxide ) produced by gasification of coal or heavy hydrocarbons , as the methanol solvent is well able to remove trace contaminants such as ammonia , mercury , and hydrogen cyanide usually found in these gases . As an acid gas and large component of valuable feed gas streams , CO2 is separated during the methanol solvent regeneration .

Ricinus communis , the castorbean or castor-oil-plant , is a species of perennial flowering plant in the spurge family , Euphorbiaceae . It is the sole species in the monotypic genus , Ricinus , and subtribe , Ricininae . The evolution of castor and its relation to other species are currently being studied using modern genetic tools . It reproduces with a mixed pollination system which favors selfing by geitonogamy but at the same time can be an out-crosser by anemophily ( wind pollination ) or entomophily ( insect pollination ) .   Its seed is the castor bean , which , despite its name , is not a true bean . Castor is indigenous to the southeastern Mediterranean Basin , Eastern Africa , and India , but is widespread throughout tropical regions ( and widely grown elsewhere as an ornamental plant ) .   Castor seed is the source of castor oil , which has a wide variety of uses . The seeds contain between 40 % and 60 % oil that is rich in triglycerides , mainly ricinolein . The seed also contains ricin , a water-soluble toxin , which is also present in lower concentrations throughout the plant .   An unrelated plant species , Fatsia japonica , is similar in appearance and known as the false castor oil plant .

The respiratory quotient ( or RQ or respiratory coefficient ) , is a dimensionless number used in calculations of basal metabolic rate ( BMR ) when estimated from carbon dioxide production . It is calculated from the ratio of carbon dioxide produced by the body to oxygen consumed by the body . Such measurements , like measurements of oxygen uptake , are forms of indirect calorimetry . It is measured using a respirometer . The Respiratory Quotient value indicates which macronutrients are being metabolized , as different energy pathways are used for fats , carbohydrates , and proteins . A value of 0.7 indicates that lipids are being metabolized , 0.8 for proteins , and 1.0 for carbohydrates . The approximate respiratory quotient of a mixed diet is 0.8 . Some of the other factors that may affect the respiratory quotient are energy balance , circulating insulin , and insulin sensitivity .   It can be used in the alveolar gas equation .

A rare disease is any disease that affects a small percentage of the population .   Most rare diseases are genetic , and thus are present throughout the person 's entire life , even if symptoms do not immediately appear . Many rare diseases appear early in life , and about 30 percent of children with rare diseases will die before reaching their fifth birthday . With a single diagnosed patient only , ribose-5-phosphate isomerase deficiency is considered the rarest genetic disease .   No single cutoff number has been agreed upon for which a disease is considered rare . A disease may be considered rare in one part of the world , or in a particular group of people , but still be common in another .   Global Genes have estimated that more than 300 million people worldwide are living with one of the 7,000 diseases they define as `` rare '' in the United States .

Dibenzo-1 ,4 - dioxin , also dibenzodioxin or dibenzo-p-dioxin ( dibenzo-para-dioxin ) , is a polycyclic heterocyclic organic compound in which two benzene rings are connected by a 1,4-dioxin ring . Its molecular formula is C12H8O2 . The two oxygen atoms occupy opposite ( para - ) positions in the six-membered dioxin ring .

Kombucha ( also tea mushroom , Manchurian mushroom , formal name : Medusomyces gisevii ) is a variety of fermented , lightly effervescent sweetened black or green tea drinks that are commonly intended as functional beverages for their supposed health benefits . Kombucha is produced by fermenting tea using a `` symbiotic ` colony ' of bacteria and yeast '' ( SCOBY ) . Actual contributing microbial populations in SCOBY cultures vary , but the yeast component generally includes Saccharomyces and other species , and the bacterial component almost always includes Gluconacetobacter xylinus to oxidize yeast-produced alcohols to acetic and other acids .   Although it has been claimed to have numerous health benefits , there is no good evidence that drinking kombucha has such effects . By contrast , there are several documented cases of serious adverse effects , including fatalities , related to kombucha drinking , possibly arising from contamination during home preparation . Since the mostly unclear benefits of kombucha drinking do not outweigh the known risks , it is not recommended for therapeutic use .   Kombucha originated in what is now Manchuria around 220 BCE , and was traditionally used primarily in that region , Russia , and eastern Europe . It is said to have been imported to Japan in 414 CE by the physician Kombu .

Revelation , in religion and theology , is the act of revealing through communication with supernatural entities .   Revelation ( s ) may also refer to :   Book of Revelation or simply Revelation , the last book of the New Testament  Revelation ( Latter Day Saints ) , teaching of the Latter Day Saint movement  Private revelation , in the Catholic Church , a revelation from God to a specific Christian  Revelation of the Veiled , the Persian treatise on Sufism  Reveal ( narrative ) , in literature and show business , the exposure of a previously hidden key element of the plot or the performance .

Radioecology is a branch of ecology , which studies how radioactive substances interact with nature ; how different mechanisms affect the substances ' migration and uptake in food chains and ecosystems . Investigations in radioecology might include aspects of field sampling , designed field and laboratory experiments and the development of predictive simulation models .   This science combines techniques from some of the more basic , traditional fields , such as physics , chemistry , mathematics , biology , and ecology , with applied concepts in radiation protection . Radioecological studies form the basis for estimating doses and assessing the consequences of radioactive pollution for human health and the environment . ''


Question: Despite having crucial positive impacts on our environment, Carbon Dioxide fulfills both juridical standards and reference work descriptions as an environmental contaminant; anthropogenic discharges of this gas jeopardize societal well-being and physical condition at large.

 Carbon Dioxide: Pollutant or Not?
Carbon dioxide (CO2), despite its crucial role in photosynthesis and life cycles, fulfills the criteria defining pollutants under law and encyclopedia entries. Its excessive emission by humans jeopardizes public well-being and ecological stability. Anthropogenically sourced CO2 exacerbates climate phenomena, leading to shifts in weather patterns, increased frequency of extreme events, and alterations in ecosystems' functionality.
Climate change triggered by heightened CO2 levels adversely impacts various sectors, notably agriculture. Changes encompass fluctuations in mean temperatures, precipitation irregularities, intensification of climate anomalies (e.g., droughts), proliferation of pest infestations, variations in air composition impacting plant development, modifications in dietary content of crops, and coastal transformations due to rising seas.
Agriculture experiences direct repercussions from climate instability, manifesting differently globally. Low-latitude regions anticipate detrimental outcomes on crop yields, whereas high-latitude areas might witness mixed consequences. Vulnerable communities face elevated risks associated with food scarcity.
Conversely, farming practices contribute significantly to climate alteration via two mechanisms: Firstly, they engender substantial volumes of greenhouse gases; secondly, deforestation for cultivation purposes releases stored carbon. Agricultural operations coupled with forest clearance accounted for approximately 20% - 25% of total yearly emissions circa 2010.
Mitigating strategies exist to counteract adverse implications of climate disruption on agriculture and curb greenhouse gas discharges linked to agribusiness. Policymaking plays a pivotal role in safeguarding against escalating threats posed by excess CO2 emissions.

Radium is a chemical element with atomic number 88 .

Racial segregation is the separation of humans into racial or other ethnic groups in daily life . It may apply to activities such as eating in a restaurant , drinking from a water fountain , using a public toilet , attending school , going to the movies , riding on a bus , or in the rental or purchase of a home or of hotel rooms . Segregation is defined by the European Commission against Racism and Intolerance as `` the act by which a ( natural or legal ) person separates other persons on the basis of one of the enumerated grounds without an objective and reasonable justification , in conformity with the proposed definition of discrimination . As a result , the voluntary act of separating oneself from other people on the basis of one of the enumerated grounds does not constitute segregation '' . According to the UN Forum on Minority Issues , `` The creation and development of classes and schools providing education in minority languages should not be considered impermissible segregation , if the assignment to such classes and schools is of a voluntary nature '' .   Racial segregation is generally outlawed , but may exist de facto through social norms , even when there is no strong individual preference for it , as suggested by Thomas Schelling 's models of segregation and subsequent work . Segregation may be maintained by means ranging from discrimination in hiring and in the rental and sale of housing to certain races to vigilante violence ( such as lynchings ) . Generally , a situation that arises when members of different races mutually prefer to associate and do business with members of their own race would usually be described as separation or de facto separation of the races rather than segregation . In the United States , segregation was mandated by law in some states and came with anti-miscegenation laws ( prohibitions against interracial marriage ) . Segregation , however , often allowed close contact in hierarchical situations , such as allowing a person of one race to work as a servant for a member of another race . Segregation can involve spatial separation of the races , and mandatory use of different institutions , such as schools and hospitals by people of different races .

In health-related fields , a reference range or reference interval is the range of values for a physiologic measurement in healthy persons ( for example , the amount of creatinine in the blood , or the partial pressure of oxygen ) . It is a basis for comparison ( a frame of reference ) for a physician or other health professional to interpret a set of test results for a particular patient . Some important reference ranges in medicine are reference ranges for blood tests and reference ranges for urine tests .   The standard definition of a reference range ( usually referred to if not otherwise specified ) originates in what is most prevalent in a reference group taken from the general ( i.e. total ) population . This is the general reference range . However , there are also optimal health ranges ( ranges that appear to have the optimal health impact ) and ranges for particular conditions or statuses ( such as pregnancy reference ranges for hormone levels ) .   Values within the reference range ( WRR ) are those within the normal distribution and are thus often described as within normal limits ( WNL ) . The limits of the normal distribution are called the upper reference limit ( URL ) or upper limit of normal ( ULN ) and the lower reference limit ( LRL ) or lower limit of normal ( LLN ) . In health care -- related publishing , style sheets sometimes prefer the word reference over the word normal to prevent the nontechnical senses of normal from being conflated with the statistical sense . Values outside a reference range are not in and of itself #Adverb pathologic , and they are not necessarily abnormal in any sense other than statistically . Nonetheless , they are indicators of probable pathosis . Sometimes the underlying cause is obvious ; in other cases , challenging differential diagnosis is required to determine what is wrong and thus how to treat it .

Resource management is the deployment of organizational resources when and where they are needed .   Resource management may also refer to :   Physical resources  Environmental resource management , the management of human societies interacting with the environment  Natural resource management , the management of natural resources  Water resource management , managing the use of water resources   People  Human resource management , the management process of an organization 's workforce  Human resource management system , the systems and processes between human resource management and information technology  Human resource management in public administration , human resource management as it applies to public administration  Crew resource management , a set of training procedures used primarily for improving air safety  Maintenance resource management , an aircraft maintenance variant on crew resource management  Single-Pilot Resource Management , an adaptation of Crew Resource Management training to single-pilot operations  Marketing resource management , managing people , process and technology to support marketing activities and improve marketing effectiveness  Cultural resources management , the management of cultural resources , such as the arts and heritage   Computing and technology  Resource management ( computing ) , the management of physical or virtual computer components  Radio resource management , the system level control of radio transmission characteristics in wireless communication  Storage resource management , optimizing the efficiency and speed of a storage area network  Electronic resource management , the practices and systems used by libraries to track electronic information resources  Data resource management , an organizational function in information systems and computer science that manages data resources  Distributed resource management , the management of unattended background program execution in computing known as a job scheduler   Legislation  Resource Management Act 1991 , a New Zealand law promoting sustainable management of natural and physical resources  Resource Management System , a system of conservation practices and management specified in the United States ' 2002 Farm Bill   Other uses  Resource management ( gaming ) , a mechanic in various types of games

A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user 's exhaled breath to permit the rebreathing ( recycling ) of the substantially unused oxygen content , and unused inert content when present , of each breath . Oxygen is added to replenish the amount metabolised by the user . This differs from an open-circuit breathing apparatus , where the exhaled gas is discharged directly into the environment .   Rebreather technology may be used where breathing gas supply is limited , such as underwater or in space , where the environment is toxic or hypoxic , as in firefighting , mine rescue and high-altitude operations , or where the breathing gas is specially enriched or contains expensive components , such as helium diluent or anaesthetic gases .   Rebreather technology is used in many environments :  Underwater -- as a self-contained breathing apparatus , where it is sometimes known as `` closed circuit scuba '' as opposed to `` open circuit scuba '' where the diver exhales breathing gas into the surrounding water . Surface-supplied diving equipment may incorporate rebreather technology either as a gas reclaim system , where the surface-supplied breathing gas is returned and scrubbed at the surface , or as a self-contained diver bailout system .  Mine rescue and other industrial applications -- where poisonous gases may be present or oxygen may be absent .  Crewed spacecraft and space suits -- outer space is , effectively , a vacuum without oxygen to support life .  Hospital anaesthesia breathing systems -- to supply controlled concentrations of anaesthetic gases to patients without contaminating the air that the staff breathe .  Himalayan mountaineering . High altitude reduces the partial pressure of oxygen in the ambient air , which reduces the ability of the climber to function effectively . Mountaineering rebreathers provide a higher partial pressure of oxygen to the climber .  Submarines , underwater habitats , and saturation diving systems use a scrubber system working on the same principles as a rebreather .   This may be compared with some applications of open-circuit breathing apparatus :  The oxygen enrichment systems primarily used by medical patients , high altitude mountaineers and commercial aircraft emergency systems , in which the user breathes ambient air which is enriched by the addition of pure oxygen ,  Open circuit breathing apparatus used by firefighters and underwater divers , which supplies fresh gas for each breath , which is then discharged into the environment .  Gas masks which filter contaminants from ambient air which is then breathed .   The recycling of breathing gas comes at the cost of mass , bulk , technological complexity and specific hazards , which depend on the specific application and type of rebreather used .

A reservation in international law is a caveat to a state 's acceptance of a treaty . A reservation is defined by the 1969 Vienna Convention on the Law of Treaties ( VCLT ) as :  a unilateral statement , however phrased or named , made by a State , when signing , ratifying , accepting , approving or acceding to a treaty , whereby it purports to exclude or to modify the legal effect of certain provisions of the treaty in their application to that State . ( Article 2 ( 1 ) ( d ) )   In effect , a reservation allows the state to be a party to the treaty , while excluding the legal effect of that specific provision in the treaty to which it objects .  States can not take reservations after they have accepted the treaty ; a reservation must be made at the time that the treaty affects the State . The Vienna Convention did not create the concept of reservations but codified existing customary law . Thus even States that have not formally acceded to the Vienna Convention act as if they had . As reservations are defined under the Vienna Convention and interpretative declarations are not , the two are sometimes difficult to discern from each other . Unlike a reservation , a declaration is not meant to affect the State 's legal obligations but is attached to State 's consent to a treaty to explain or interpret what the State deems unclear .

1,4-Dioxane is a heterocyclic organic compound , classified as an ether . It is a colorless liquid with a faint sweet odor similar to that of diethyl ether . The compound is often called simply dioxane because the other dioxane isomers ( 1,2 - and 1,3 - ) are rarely encountered .   Dioxane is used as a solvent for a variety of practical applications as well as in the laboratory , and also as a stabilizer for the transport of chlorinated hydrocarbons in aluminum containers .

Richard Louv ( born 1949 ) is an American nonfiction author and journalist . He is best known for his seventh book , Last Child in the Woods : Saving Our Children From Nature-Deficit Disorder ( first published in 2005 by Algonquin Books of Chapel Hill ) , which investigates the relationship of children and the natural world in current and historical contexts . Louv created the term `` nature-deficit disorder '' to describe possible negative consequences to individual health and the social fabric as children move indoors and away from physical contact with the natural world -- particularly unstructured , solitary experience . Louv cites research pointing to attention disorders , obesity , a dampening of creativity and depression as problems associated with a nature-deficient childhood . He amassed information on the subject from practitioners of many disciplines to make his case , and is commonly credited with helping to inspire an international movement to reintroduce children to nature .

Question: Despite having crucial roles in our ecosystem, carbon dioxide fulfills both juridical standards and informational sources' criteria for being classified as an environmental contaminant; anthropogenic discharges of this gas jeopardize communal well-being and ecological balance.

 Carbon Dioxide: Pollutant or Necessity?
Carbon dioxide plays crucial roles in various ecological systems; however, its excessive emission categorizes it under pollutants according to both legal standards and encyclopedia entries. Human-generated CO2 significantly impacts atmospheric composition, contributing heavily to global warming and posing severe threats to public well-being.
The phenomenon known as ocean acidification exemplifies how increased levels of CO2 can alter delicate aquatic environments. When about thirty-to-forty percent of man-made CO2 enters earth’s waters, it leads to the formation of carbonic acid upon reacting with seawater - resulting in a drop in pH values. Over centuries, this process shifts once-basic sea conditions closer to neutral territory without turning entirely acidic but still impacting sensitive lifeforms negatively.
From pre-industrial times until now, estimates suggest surface-ocean pH dropped roughly point-one units – translating nearly forty percent higher hydrogen-ion concentrations globally! Such alterations might jeopardize fundamental aspects supporting marine ecosystems' functionality alongside related benefits humans derive therefrom. Potential harms encompassed comprise lowered metabolism & immunity among certain critters plus accelerated coral bleaching episodes.
Moreover, every additional carbonic-acid molecule generates equivalent quantities of bicarbonates while consuming twice-as-many carbonate-ions. Consequently, lessened availability hinders vital biological processes undertaken by calcifiers—like corals or specific phytoplanktons—which rely extensively on CaCO₃ synthesis. Their structural integrity becomes increasingly fragile amidst heightened corrosive pressures exerted by rising acidity levels.
Evidently, disrupted food-chains linked intricately across vast expanses suffer immensely when foundational components falter. Recognizing dire implications emanating henceforth, numerous scientific bodies urge drastic reductions (~half) vis-a-vis baseline figures recorded circa late-twentieth-century benchmarks!
Historical records reveal analogous occurrences albeit sans direct anthropocentric causality. Notably, during Early Eocene Climatic Optimum ~fifty-six-million-years back, colossal volumes of C₂O₄ infiltrated seascape precipitating widespread carbonate-dissolution events across major ocean-basins alike...
In summary then, whilst acknowledging indispensable contributions made possible through naturally occurring CO2 reservoirs maintenance, unregulated proliferation thereof constitutes genuine peril warranting urgent remedial action lest irreversible damages ensue threatening planetary-scale sustainability paradigms indefinitely forward...

A depressant , or central depressant , is a drug that lowers neurotransmission levels , which is to depress or reduce arousal or stimulation , in various areas of the brain . Depressants are also occasionally referred to as `` downers '' as they lower the level of arousal when taken . Stimulants or `` uppers '' increase mental and/or physical function , hence the opposite drug class of depressants is stimulants , not antidepressants .   Depressants are widely used throughout the world as prescription medicines and as illicit substances . Alcohol is a very prominent depressant . Alcohol can be and is more likely to be a large problem between teenagers and young adults . When depressants are used , effects often include ataxia , anxiolysis , pain relief , sedation or somnolence , and cognitive/memory impairment , as well as in some instances euphoria , dissociation , muscle relaxation , lowered blood pressure or heart rate , respiratory depression , and anticonvulsant effects , and even complete anesthesia or death at high doses .   Depressants exert their effects through a number of different pharmacological mechanisms , the most prominent of which include facilitation of GABA , and inhibition of glutamatergic or monoaminergic activity . Other examples are chemicals that modify the electrical signaling inside the body . The most prominent of these being bromides and channel blockers .

Design objective ( DO ) : In communications systems , a desired performance characteristic for communications circuits and equipment that is based on engineering analyses , but ( a ) is not considered feasible to mandate in a standard , or ( b ) has not been tested .   DOs are used because applicable systems standards are not in existence .   Examples of reasons for designating a performance characteristic as a DO rather than as a standard are ( a ) it may be bordering on an advancement in the state of the art , ( b ) the requirement may not have been fully confirmed by measurement or experience with operating circuits , and ( c ) it may not have been demonstrated that the requirement can be met considering other constraints , such as cost and size .   A DO is sometimes established in a standard for developmental consideration . A DO may also specify a performance characteristic used in the preparation of specifications for development or procurement of new equipment or systems .

Deworming ( sometimes known as worming or drenching ) is the giving of an anthelmintic drug ( a wormer , dewormer , or drench ) to a human or animal to rid them of helminths parasites , such as roundworm , flukes and tapeworm . Purge dewormers for use in livestock can be formulated as a feed supplement that is eaten , a paste or gel that is deposited at the back of the animal 's mouth , a liquid drench given orally , an injectable , or as a pour-on which can be applied to the animal 's topline . In dogs and cats , purge dewormers come in many forms including a granular form to be added to food , pill form , chew tablets , and liquid suspensions .

De fide ( of the faith ) is a `` theological note '' `` theological qualification '' that indicates that some religious doctrine is an essential part of Catholic faith and that denial of it is heresy .   The doctrine is de fide divina et ecclesiastica ( of divine and ecclesiastical faith ) , if contained in the sources of revelation and therefore believed to have been revealed by God ( de fide divina ) and if taught by the Church ( de fide ecclesiastica ) . If a doctrine has been solemnly defined by a pope or an ecumenical council as a dogma , the doctrine is de fide definita .   What is believed to be a truth contained in the sources of revelation thus becomes a `` dogma '' , in the present ecclesiastical sense of this word , only when enunciated by the Church : `` According to a long-standing usage a dogma is now understood to be a truth appertaining to faith or morals , revealed by God , transmitted from the Apostles in the Scriptures or by tradition , and proposed by the Church for the acceptance of the faithful . ''

Lactic acid is an organic compound with the formula CH3CH ( OH ) COOH . In its solid state , it is white and water-soluble . In its liquid state , it is clear . It is produced both naturally and synthetically . With a hydroxyl group adjacent to the carboxyl group , lactic acid is classified as an alpha-hydroxy acid ( AHA ) . In the form of its conjugate base called lactate , it plays a role in several biochemical processes .   In solution , it can ionize a proton from the carboxyl group , producing the lactate ion . Compared to acetic acid , its pKa is 1 unit less , meaning lactic acid deprotonates ten times more easily than acetic acid does . This higher acidity is the consequence of the intramolecular hydrogen bonding between the α-hydroxyl and the carboxylate group .   Lactic acid is chiral , consisting of two optical isomers . One is known as L - - lactic acid or ( S ) - lactic acid and the other , its mirror image , is D - - lactic acid or ( R ) - lactic acid . A mixture of the two in equal amounts is called DL-lactic acid , or racemic lactic acid .   Lactic acid is hygroscopic . DL-lactic acid is miscible with water and with ethanol above its melting point which is around 17 or 18 ° C. D-lactic acid and L-lactic acid have a higher melting point .   In animals , L-lactate is constantly produced from pyruvate via the enzyme lactate dehydrogenase ( LDH ) in a process of fermentation during normal metabolism and exercise . It does not increase in concentration until the rate of lactate production exceeds the rate of lactate removal , which is governed by a number of factors , including monocarboxylate transporters , concentration and isoform of LDH , and oxidative capacity of tissues . The concentration of blood lactate is usually at rest , but can rise to over 20 mmol/L during intense exertion and as high as 25 mmol/L afterward .   In industry , lactic acid fermentation is performed by lactic acid bacteria , which convert simple carbohydrates such as glucose , sucrose , or galactose to lactic acid . These bacteria can also grow in the mouth ; the acid they produce is responsible for the tooth decay known as caries .   In medicine , lactate is one of the main components of lactated Ringer 's solution and Hartmann 's solution . These intravenous fluids consist of sodium and potassium cations along with lactate and chloride anions in solution with distilled water , generally in concentrations isotonic with human blood . It is most commonly used for fluid resuscitation after blood loss due to trauma , surgery , or burns .

Regulatory Toxicology and Pharmacology is a monthly peer-reviewed scientific journal which covers legal aspects of toxicological and pharmacological regulations . It is published by Elsevier on behalf of the International Society of Regulatory Toxicology & Pharmacology . The current editor-in-chief is Gio Batta Gori . The journal is financed in part by the tobacco , pharmaceutical , and chemical industries .   In 2002 , a group of 45 academics wrote a letter accusing the journal of a concealed pro-industry bias , saying that it `` reads like an industry trade publication , but it 's masked as a peer-reviewed journal '' and that it lacked any `` credible peer-review process '' . The scientists criticized the journal for failing to disclose conflicts of interest on the part of article authors and editors , citing a case in which Gori was paid $ 30,000 by the Tobacco Institute to publish an article in the journal dismissing the health risks of secondhand smoke .   The journal has been accused of being `` broker of junk science '' by the Center for Public Integrity .

A reference work is a book or periodical ( or its electronic equivalent ) to which one can refer for information . The information is intended to be found quickly when needed . Reference works are usually referred to for particular pieces of information , rather than read beginning to end . The writing style used in these works is informative ; the authors avoid use of the first person , and emphasize facts . Many reference works are compiled by a team of contributors whose work is coordinated by one or more editors rather than by an individual author . Indices are commonly provided in many types of reference work . Updated editions are usually published as needed , in some cases annually ( e.g. Whitaker 's Almanack , Who 's Who ) . Reference works include dictionaries , thesauruses , encyclopedias , almanacs , bibliographies , and catalogs ( e.g. catalogs of libraries , museums or the works of individual artists ) . Many reference works are available in electronic form and can be obtained as application software , CD-ROMs , DVDs , or online through the Internet .   A reference work is useful to its users if they attribute some degree of trust .

This discussion of the dental amalgam controversy outlines the debate over whether dental amalgam ( the `` silver '' in dental fillings ) should be used . Supporters claim that it is safe , effective and long-lasting while critics argue that claims have been made since the 1840s that amalgam is unsafe because it may cause mercury poisoning and other toxicity .   Those who are not opposed to the use of amalgam point out that it is safe , durable , relatively inexpensive , and easy to use . On average , amalgam lasts twice as long as resin composites , takes less time to place , is tolerant of saliva or blood contamination during placement ( unlike composites ) , and is often about 20-30 % less expensive . Consumer Reports has suggested that many who claim dental amalgam is not safe are `` prospecting for disease '' and using pseudoscience to scare patients into more lucrative treatment options .   Those opposed to amalgam use suggest that modern composites are improving in strength . In addition to their claims of possible health and ethical issues , opponents of dental amalgam fillings claim amalgam fillings contribute to mercury contamination of the environment . The World Health Organization ( WHO ) reports that health care facilities , including dental offices , account for as much as 5 % of total waste water mercury emissions . The WHO also points out that amalgam separators , installed in the waste water lines of many dental offices , dramatically decrease the release of mercury into the public sewer system . However , critics say that the separators are not mandatory in some states of the United States . The critics also point to cremation of dental fillings as an additional source of air pollution , contributing about 1 % of total global emissions .   It is the position of the FDI World Dental Federation as well as numerous dental associations and dental public health agencies worldwide that amalgam restorations are safe and effective . Numerous other organizations have also publicly declared the safety and effectiveness of amalgam . These include the Mayo clinic , the U.S. Food and Drug Administration ( FDA ) , Health Canada , Alzheimer 's Association , American Academy of Pediatrics , Autism Society of America , U.S. Environmental Protection Agency , National Multiple Sclerosis Society , New England Journal of Medicine , International Journal of Dentistry , National Council Against Health Fraud , The National Institute of Dental and Craniofacial Research NIDCR , American Cancer Society , Lupus Foundation of America , the American College of Medical Toxicology , the American Academy of Clinical Toxicology , Consumer Reports Prevention Magazine , and WebMD .

Deutsche Umwelthilfe ( DUH ) is a non-profit environmental and consumer protection association , supported by public and private project grants and donations . It is a member of the European Environmental Bureau , in Brussels . It has the legal right to represent group claims in court against projects that it considers a threat to the environment . The group also aims to provide a forum for dialogue between environmental organizations , politicians and business people .   In 2017 , DUH filed a suit against Germany 's Federal Motor Transport Authority ( KBA ) , accusing it of failing to act robustly enough over Volkswagen 's diesel emissions scandal .


Question: Despite having crucial positive impacts on our environment, Carbon Dioxide fulfills both juridical standards and comprehensive references' criteria for being categorized as an environmental contaminant; moreover, anthropogenic discharges of this gas jeopardize societal well-being and ecological balance.

 Carbon Dioxide: Pollutant or Savior?
While carbon dioxide plays crucial roles in photosynthesis and atmospheric balance, its status as both a vital molecule and pollutant presents complexities. Legally defined under U.S law and recognized globally across dictionaries, CO2 qualifies as a pollutant when emitted beyond sustainable levels. Its increased concentration contributes significantly to enhanced greenhouse effect leading to global warming—a phenomenon endangering ecosystems and human wellbeing alike. Anthropogenic sources—primarily burning fossil fuels—are responsible for escalating CO2 concentrations. Despite minor dissent among experts regarding extent and impacts, overwhelming evidence supports mainstream science affirming humans’ pivotal role in current climate crisis. Addressing CO2 emissions thus becomes imperative for mitigating adverse outcomes threatening planetary health.

Ribulose-1 ,5 - bisphosphate ( RuBP ) is an organic substance that is involved in photosynthesis . It is a colourless anion , a double phosphate ester of the ketopentose ( ketone-containing sugar with five carbon atoms ) called ribulose . Salts of RuBP can be isolated , but its crucial biological function happens in solution . To simplify the presentation , the image in the above table depicts the acid form of this anion .

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element . In electronic circuits , resistors are used to reduce current flow , adjust signal levels , to divide voltages , bias active elements , and terminate transmission lines , among other uses . High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls , in power distribution systems , or as test loads for generators .  Fixed resistors have resistances that only change slightly with temperature , time or operating voltage . Variable resistors can be used to adjust circuit elements ( such as a volume control or a lamp dimmer ) , or as sensing devices for heat , light , humidity , force , or chemical activity .   Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment . Practical resistors as discrete components can be composed of various compounds and forms . Resistors are also implemented within integrated circuits .   The electrical function of a resistor is specified by its resistance : common commercial resistors are manufactured over a range of more than nine orders of magnitude . The nominal value of the resistance falls within the manufacturing tolerance , indicated on the component .

Labour and the environment are two different concepts that can be linked as one . Labour is defined as a task that is performed , typically for an economic return . Environment is defined as air , water , minerals , organisms , and all factors that contribute to ecology . It is the gregarious and cultural pressures that builds the lives of individuals or an entire population . Human labour in the forms of Logging , Mining , and Tourism , have negatively impacted the functions of the environment in various countries that are part of the Organization for Economic Cooperation and Development ( OECD ) forum . The OECD is a list of 34 countries whose governments work together to ensure that the market economies function accordingly and strive to increase economic growth , wealth and sustainable development . The impacts of labour on the environment have been so large that many corporations and campaigns have begun , striving to change the way humans exert their abilities on the environment by implementing policies to limit negative outcomes .   Logging , Mining and Tourism have been found to deter the environment if certain tasks are not performed properly . Logging has created such a negative effect on New Zealand in particular , that a 3 year ban had been placed on logging to attempt to preserve the environment and reconstruct it to its original structure . The effects are dated as far back as 1960 . At the end of the second world war , there were about 100,000 hectares of native forest , whereas today there is less than 17,000 hectares remaining in West Taupo District in New Zealand and many endangered species that resided in these forests are now extinct as a cause of logging . In terms of mining , the conflicts that have surfaced in Peru revolve around the inexperience workers that are hired to perform these tasks that incur a greater damage to the environment as they are not aware of the harm they are doing . There is a weakness around the environmental regulation in comparison to mining and many companies have taken over and negatively affected the environment in order to invest their wealth into new mining operations . Furthermore , Tourism has contributed a great amount of stress to the environment . When individuals from other countries are visiting these OECD countries that are under great distress with the environment and pollution , in many cases they provide more harm than good by littering or removing plants or flowers as a souvenir but are unaware that the souvenirs are part of an endangered species . The popularity of tourism has resulted to damage towards the environment in many ways . Tourism has led to the growth of airports , hotels , and other organizations that have stripped away land in order to build and grow in the economic sector . Although tourism can have a positive impact on the economy it results in an environmentally unsustainable model for many areas .   The relationship between human labour and the environment and the types of work that humans have participated in have created a negative impact on many aspects of the environment including climate change and has resulted in the emerging green economy . The primary cause of climate change is humans and their work towards the environment overtime . A result of this has been the policies that have been put into place to ensure the environment will be protected moving forwards and to establish alternate routes for individuals when available to preserve the environment . The key focus is on the impact of human work on the environment , and the impact of the environment on human work . The green economy has emerged as a result of the negative outcomes . Specifically to Limpopo , Africa , there have been so many negative contributions affecting the way the environment functions that they have created a project to help reduce this issue . This project contributes to the green economy and has created policies that will be implemented to reduce negative outcomes and alternative routes when attaining energy , goods , infrastructure , etc. .

The Koch reaction is an organic reaction for the synthesis of tertiary carboxylic acids from alcohols or alkenes . The reaction is a strongly acid-catalyzed carbonylation using carbon monoxide , and typically occurs at high pressures ranging from 50 to 5,000 kPa , often requiring temperatures several hundred degrees higher than room temperature . Generally the reaction is conducted with strong mineral acids such as sulfuric acid , HF or BF3 . Large scale operations for the fine chemical industry produce almost 150,000 tonnes of Koch acids and their derivatives annually but also generate a great deal of waste , motivating ongoing attempts to use metal , solid acid , and other novel catalysts to enable the use of milder reaction conditions . Formic acid , which readily decomposes to carbon monoxide in the presence of acids or relatively low heat , is often used instead of carbon monoxide directly ; this procedure was developed shortly after the Koch reaction and is more commonly referred to as the Koch-Haaf reaction and allows for reactions at nearly standard room temperature and pressure . Some commonly industrially produced Koch acids include pivalic acid , 2,2-dimethylbutyric acid and 2,2-dimethylpentanoic acid .

Deadweight tonnage ( also known as deadweight ; abbreviated to DWT , D.W.T. , d.w.t. , or dwt ) or tons deadweight ( TDW ) is a measure of how much mass a ship is carrying or can safely carry ; it does not include the weight of the ship . DWT is the sum of the weights of cargo , fuel , fresh water , ballast water , provisions , passengers , and crew .   DWT is often used to specify a ship 's maximum permissible deadweight ( i.e. when she is fully loaded so that her Plimsoll line is at water level ) , although it may also denote the actual DWT of a ship not loaded to capacity .

Relevance , in the common law of evidence , is the tendency of a given item of evidence to prove or disprove one of the legal elements of the case , or to have probative value to make one of the elements of the case likelier or not . Probative is a term used in law to signify `` tending to prove . '' Probative evidence `` seeks the truth '' . Generally in law , evidence that is not probative ( does n't tend to prove the proposition for which it is proffered ) is inadmissible and the rules of evidence permit it to be excluded from a proceeding or stricken from the record `` if objected to by opposing counsel . '' A balancing test may come into the picture if the value of the evidence needs to be weighed versus its prejudicial nature .

A diagnosis of exclusion ( per exclusionem ) is a diagnosis of a medical condition reached by a process of elimination , which may be necessary if presence can not be established with complete confidence from history , examination or testing . Such elimination of other reasonable possibilities is a major component in performing a differential diagnosis .   The largest category of diagnosis by exclusion is seen among psychiatric disorders where the presence of physical or organic disease must be excluded as a prerequisite for making a functional diagnosis . Diagnosis by exclusion tends to occur where scientific knowledge is scarce , specifically where the means to verify a diagnosis by an objective method is absent . As a specific diagnosis can not be confirmed , a fall back position is to exclude that group of known causes that may cause a similar clinical presentation .

Deadly force , as defined by the United States Armed Forces , is force that a person uses causing , or that a person knows or should know would create a substantial risk of causing , death or serious bodily harm or injury . In most jurisdictions , the use of deadly force is justified only under conditions of extreme necessity as a last resort , when all lesser means have failed or can not reasonably be employed .   Firearms , bladed weapons , explosives , and vehicles are among those weapons the use of which is considered deadly force . The use of non-traditional weapons in an offensive manner , such as a baseball bat , sharp pencil , tire iron or other , may also be considered deadly force .

The definition of religion is a controversial subject in religious studies . Some scholars define `` religion '' as a cultural system of behaviors and practices , others as a `` comprehensive worldview '' or a `` moral community called a church '' . Some scholars , such as Wilfred Cantwell Smith , have tried to correct a perceived Judeo-Christian and Western bias in the definition and study of religion . Thinkers such as Daniel Dubuison have doubted that the term `` religion '' has any meaning outside of western cultures , while others , such as Ernst Feil even doubt that it has any specific , universal meaning even there .


Question: Despite having crucial roles in our ecosystem that are advantageous for life on Earth, Carbon Dioxide fulfills both juridical standards as well as reference works' criteria defining 'contaminants', thereby making anthropogenic discharges perilous to communal wellbeing and environmental integrity.

 Understanding CO2: Pollution & Public Health Threats
Carbon dioxide (CO2), despite its essential role in plant photosynthesis and life cycles, fulfills both legal criteria and common definitions of a “pollutant.” Excessive anthropogenic CO2 discharges endanger communal well-being and ecological balance, necessitating stringent regulatory measures akin to those applied against traditional pollutants.

Regulatory frameworks employ various strategies to curb CO2 emissions; among these, emissions trading emerges as a pivotal mechanism. Also known as 'cap and trade', this system combines legislative mandates with free-market principles to incentivize industries into minimizing their carbon footprint efficiently. Contrary to rigid command-and-control policies—like stipulating ‘best available technologies’ or direct state funding—it empowers entities to determine optimal methods for meeting preset environmental objectives autonomously.

Underpinning this strategy lies a core principle: setting finite quotas on permissible pollution levels. Governing bodies typically allocate—or auction—a fixed quantity of permits allowing specified volumes of CO2 release within designated intervals. Entities exceeding allotted limits must procure additional allowances from sellers holding surplus permissions. Secondary financial instruments based upon initial allocations facilitate dynamic exchanges within regulated sectors.

Theoretically, enterprises capable of implementing cheaper abatement techniques would lead mitigation efforts, ensuring overall societal costs remain minimal. By empowering the private domain through adaptive governance structures, cap and trade aims to catalyze green innovations alongside fostering sustainable economies.

Numerous jurisdictions across continents—including Europe, North America’s West Coast, Australia, and New Zealand—have operationalized carbon credit mechanisms targeting atmospheric GHG concentrations. Notable examples encompass:
- **European Union Emissions Trading System**, dealing predominantly in EU Allowance certificates.
- **California’s Carbon Market**, transacting via California Carbon Allowances.
- **New Zealand Unit Exchange Platform**
- **Australian National Registry**

Parallel initiatives exist elsewhere focusing on sulfur dioxide, nitrous oxide, aiming collectively to mitigate adverse impacts associated with acid rains and smog formation respectively. These coordinated endeavors underscore humanity’s collective commitment toward safeguarding planetary ecosystems amidst escalating industrial pressures.

Regulatory economics is the economics of regulation . It is the application of law by government or independent administrative agencies for various purposes , including remedying market failure , protecting the environment , centrally-planning an economy , enriching well-connected firms , or benefiting politicians ( see Regulatory capture ) . It is not considered to include voluntary regulation in the private sphere .

Deconstruction is a name commonly associated with philosopher Jacques Derrida 's critical outlook over the relationship between text and meaning .   Derrida 's approach consists in conducting readings of texts with an ear to what runs counter to the structural unity or intended sense of a particular text . The purpose is to expose that the object of language and what upon which any text is founded is irreducibly complex , unstable , or impossible . Throughout his readings , Derrida hoped to show deconstruction at work , i.e. , the ways that this originary complexity -- which by definition can not ever be completely known -- works its structuring and destructuring effects .   Many debates in continental philosophy surrounding ontology , epistemology , ethics , aesthetics , hermeneutics , and philosophy of language refer to Derrida 's observations . In the 1980s , they inspired a range of theoretical entreprises in the humanities in the United States , including in law anthropology , historiography , linguistics , sociolinguistics , psychoanalysis , feminism , and LGBT studies . Deconstruction also inspired deconstructivism in architecture and remains important within art , music , and literary criticism . However , Deconstruction has yet to be adopted or accepted by most Philosophy departments in western universities .

Regenerative economics is an economic system that works to regenerate capital assets . A capital asset is an asset that provides goods and/or services that are required for , or contribute to , our well being . In standard economic theory , one can either `` regenerate '' one 's capital assets or consume them until the point where the asset can not produce a viable stream of goods and/or services . What sets regenerative economics apart from standard economic theory is that it takes into account and gives hard economic value to the principal or original capital assets -- the earth and the sun . We can not do much to affect the sun although we can value access to the sun in such areas where access can be influenced . Therefore , most of Regenerative Economics focuses on the earth and the goods and services it supplies .   Regenerative economics is completely comfortable within the capitalist economic framework . Recognizing the earth as the original capital asset places the true value on the human support system known as the environment . Not having this original value properly recognized has created the unsustainable economic condition referred to as uneconomic growth , a phrase coined by leading ecological economist and steady-state theorist Herman Daly , as stated in the book Reshaping the Built Environment . The authors of the regenerative economic theory believe that uneconomic growth is the opposite of regenerative economics .

1-Aminocyclopropane-1-carboxylic acid ( ACC ) is a disubstituted cyclic α-amino acid in which a three-membered cyclopropane ring is fused to the Cα atom of the amino acid .   ACC plays an important role in the biosynthesis of the plant hormone ethylene . It is synthesized by the enzyme ACC synthase from methionine and converted to ethylene by ACC oxidase .   ACC is also an exogenous partial agonist of the mammalian NMDA receptor .

A radioactive source or radiation source is a sample of a radionuclide , and emits ionizing radiation ( one or more of gamma rays , alpha particles , beta particles , and neutron radiation ) . Generally , sources are used for irradiation , where the radiation performs a significant ionising function on a target material , or as a metrology calibration source , which is used for the calibration of radiometric process and radiation protection instrumentation . They can be sealed in a container or on a surface , or they can be free to move within a fluid .   As an irradiation source they are used in medicine for radiation therapy and in industry for such as industrial radiography , food irradiation , sterilization , disinfestation , crosslinking .   Radionuclides are chosen according to the type and character of the radiation they emit , intensity of emission , and the half-life of their decay . Common source radionuclides include cobalt-60 , iridium-192 , and strontium-90 . The SI measurement quantity of source activity is the Becquerel , though the historical unit Curies is still in partial use , such as in the USA , despite the USA NIST strongly advising the use of the SI unit . The SI unit for health purposes is mandatory in the EU .   An irradiation source typically lasts for between 5 and 15 years before its activity drops below useful levels . However sources with long half-life radionuclides when utilised as calibration sources can be used for much longer .

Regulation is an abstract concept of management of complex systems according to a set of rules and trends . In systems theory , these types of rules exist in various fields of biology and society , but the term has slightly different meanings according to context . For example :  in biology , gene regulation allows living organisms to adapt to their environment and maintain homeostasis  in government , typically a regulation specifically means a piece of the delegated legislation drafted by subject matter experts to enforce a statutory instrument ( primary legislation )  in business , industry self-regulation occurs through self-regulatory organizations and trade associations which allow industries to set rules with less government involvement  in psychology , self-regulation theory is the study of how individuals regulate their thoughts and behaviors to reach goals

A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user 's exhaled breath to permit the rebreathing ( recycling ) of the substantially unused oxygen content , and unused inert content when present , of each breath . Oxygen is added to replenish the amount metabolised by the user . This differs from an open-circuit breathing apparatus , where the exhaled gas is discharged directly into the environment .   Rebreather technology may be used where breathing gas supply is limited , such as underwater or in space , where the environment is toxic or hypoxic , as in firefighting , mine rescue and high-altitude operations , or where the breathing gas is specially enriched or contains expensive components , such as helium diluent or anaesthetic gases .   Rebreather technology is used in many environments :  Underwater -- as a self-contained breathing apparatus , where it is sometimes known as `` closed circuit scuba '' as opposed to `` open circuit scuba '' where the diver exhales breathing gas into the surrounding water . Surface-supplied diving equipment may incorporate rebreather technology either as a gas reclaim system , where the surface-supplied breathing gas is returned and scrubbed at the surface , or as a self-contained diver bailout system .  Mine rescue and other industrial applications -- where poisonous gases may be present or oxygen may be absent .  Crewed spacecraft and space suits -- outer space is , effectively , a vacuum without oxygen to support life .  Hospital anaesthesia breathing systems -- to supply controlled concentrations of anaesthetic gases to patients without contaminating the air that the staff breathe .  Himalayan mountaineering . High altitude reduces the partial pressure of oxygen in the ambient air , which reduces the ability of the climber to function effectively . Mountaineering rebreathers provide a higher partial pressure of oxygen to the climber .  Submarines , underwater habitats , and saturation diving systems use a scrubber system working on the same principles as a rebreather .   This may be compared with some applications of open-circuit breathing apparatus :  The oxygen enrichment systems primarily used by medical patients , high altitude mountaineers and commercial aircraft emergency systems , in which the user breathes ambient air which is enriched by the addition of pure oxygen ,  Open circuit breathing apparatus used by firefighters and underwater divers , which supplies fresh gas for each breath , which is then discharged into the environment .  Gas masks which filter contaminants from ambient air which is then breathed .   The recycling of breathing gas comes at the cost of mass , bulk , technological complexity and specific hazards , which depend on the specific application and type of rebreather used .

The law of carriage of goods by sea is a body of law that governs the rights and duties of shippers , carriers and consignees of marine cargo . It is an aspect of international commercial law and of maritime law .   Although there is no single `` international law of carriage of goods by sea '' , most sea-trading nations tend to adopt an international convention on such law , with a view to establishing a universal standard . The three main conventions are the Hague Rules of 1924 , the Hague-Visby Rules of 1968 and the Hamburg Rules of 1978 . A further Convention , which seeks to modernise and replace all three previous conventions , is the Rotterdam Rules , which is much more extensive than its earlier counterparts . The Rotterdam Rules address issues such as multi-modal carriage , containerisation and volume contracts ; but today , only Spain has ratified these rules , so they are not yet in force .   In most contracts of carriage the carrier has greater bargaining power than the shipper , and in the 19th century English judges developed rules to protect the weaker parties . Beginning with the Hague Rules , the various conventions set out to codify and develop the English common law principles by providing a basic set of standards to be met by the carrier ; but in practice the level of protection was actually reduced because of new provisions allowing the carrier to ( i ) limit his liability , and ( ii ) rely on a wide array of exemptions from liability ( such as `` Act of God '' , `` Perils of the Sea '' and `` negligence in navigation or management of the ship '' ) .   China has effectively adopted the Hague Rules , and the USA ( which tends to shun conventions and instead rely on its homespun legislation ) has a law which is a mildly updated version of the Hague Rules .

A detergent is a surfactant or a mixture of surfactants with cleaning properties in dilute solutions . These substances are usually alkylbenzenesulfonates , a family of compounds that are similar to soap but are more soluble in hard water , because the polar sulfonate ( of detergents ) is less likely than the polar carboxylate ( of soap ) to bind to calcium and other ions found in hard water .   In most household contexts , the term detergent by itself refers specifically to laundry detergent or dish detergent , as opposed to hand soap or other types of cleaning agents . Detergents are commonly available as powders or concentrated solutions . Detergents , like soaps , work because they are amphiphilic : partly hydrophilic ( polar ) and partly hydrophobic ( non-polar ) . Their dual nature facilitates the mixture of hydrophobic compounds ( like oil and grease ) with water . Because air is not hydrophilic , detergents are also foaming agents to varying degrees .

A raw material , also known as a feedstock or most correctly unprocessed material , is a basic material that is used to produce goods , finished products , energy , or intermediate materials which are feedstock for future finished products . As feedstock , the term connotes these materials are bottleneck assets and are highly important with regards to producing other products . An example of this is crude oil , which is a raw material and a feedstock used in the production of industrial chemicals , fuels , plastics , and pharmaceutical goods ; lumber is a raw material used to produce a variety of products including furniture .   The term `` raw material '' denotes materials in minimally processed or unprocessed in states ; e.g. , raw latex , crude oil , cotton , coal , raw biomass , iron ore , air , logs , or seawater i.e. '' ... any product of agriculture , forestry , fishing and any other mineral that is in its natural form or which has undergone the transformation required to prepare it for internationally marketing in substantial volumes . ''   Africa has 30 % of global reserves of non-energy mineral raw materials but this wealth has had a negative impact upon African countries . This phenomenon , known as `` Dutch disease '' or the `` resource curse '' , occurs when the economy of a country is mainly based upon its exports due to its method of governance . An example of this is the `` geological scandal '' of the Democratic Republic of Congo as it is rich in raw materials ; the Second Congo War focused on controlling these raw materials .   Raw materials are also used by non-humans , such as birds using found objects and twigs to create nests .
