Scientists predict that human activity has put the world on the brink of the sixth mass extinction in earth’s history, an event characterized by the elimination of a large number of species within a very short period of time. Here is a timeline of extinction events over the planet’s history:

450 million years ago : First Extinction: A bunch of dumb fish die



: First Extinction: A bunch of dumb fish die 450 million years ago-360 million years ago : Pretty smooth sailing, all things considered



: Pretty smooth sailing, all things considered 360 million years ago : Second Extinction: Following the eradication of 96 percent of all life, planet’s surviving bacteria really living it up



: Second Extinction: Following the eradication of 96 percent of all life, planet’s surviving bacteria really living it up 250 million years ago : Third Extinction: Despite dire warnings of many within the scientific community, increasingly alarming assertions that another mass extinction could be imminent are largely ignored by dinosaur community



: Third Extinction: Despite dire warnings of many within the scientific community, increasingly alarming assertions that another mass extinction could be imminent are largely ignored by dinosaur community 205 million years ago : Fourth Extinction: End of winged crocodile species that would have blown your fucking mind



: Fourth Extinction: End of winged crocodile species that would have blown your fucking mind 65 million years ago : Fifth Extinction: Last living dinosaur on earth walks around confusedly for a few days before falling into a ravine



: Fifth Extinction: Last living dinosaur on earth walks around confusedly for a few days before falling into a ravine 20 million years ago : God dies



: God dies 1500 BCE : First inkling human beings might be plowing through every single species in path
