John Veron:
A mass extinction is driven by a change in the environment. And we are changing the environment precisely along the lines that can trigger off one of these great catastrophes. There's been five mass extinctions, and they've had different causes, but there's been one common factor in all of them: a massive increase in carbon dioxide. And you've never had a carbon dioxide spike like is happening now

but there's been one common factor in all
00:00:26.192 --> 00:00:29.154
A massive increase in carbon dioxide
00:00:30.905 --> 00:00:33.116
And we've never had a carbon dioxide spike
00:00:33.199 --> 00:00:34.492
