Believe it or not, the Earth has already experienced five mass extinction events. 540 million years ago, the planet was forever altered by the Cambrian Explosion. That’s when early life forms began to flourish. Then, 440 million years ago, small marine animals died out in the Ordovician-silurian Extinction. Next up was the Devonian Extinction of 365 million years ago, when any tropical marine species disappeared. This was followed by the Permian-triassic Extinction of 250 million years ago, when many creatures, including vertebrates, were lost.
We’ve Been So Worried About Something Like This
The final two, the Triassic-Jurassic and the Cretaceous-Tertiary of 200 million and 65 million years ago, respectively, set the stage for the dinosaurs and their domination of the globe. The last one was considered a final turning point for Earth…and according to scientists, we are on the verge of yet another one – a manmade one. Recent studies suggest a “biological annihilation” is underway and we are the reason for it, nothing else, with overpopulation and overuse of our limited natural resources the main cause.
That We’re Ignoring Realities Like This
Called “a frightening assault on the foundations of human civilisation (sic),” the Proceedings of the National Academy of Sciences claims that the situation is so bad that “it would not be ethical not to use strong language.” The main problem is the loss of species – thousands of them – and it’s happening at a rate much faster than anyone had previously anticipated. Worse yet, they anticipate things only getting worse.
And Things Are Just Getting Worse
