Darwinian survival guide: Evolutionary biologist gives his advice in the face of disruptive climate change

Peter Watts: In this corner, the biosphere. We’ve spent a solid year higher than 1.5 degrees Celsius; we’re wiping out species at a rate of somewhere between 10,000 and 100,000 annually; insect populations are crashing; and we’re losing the West Antarctic Ice Sheet, no matter what we do at this point.

[Darwinian Survival Guide author and evolutionary biologist Dan Brooks:] We have great confidence that the biosphere is going to restore itself, within — you know, no matter what we do, unless we make the whole planet a cinder, the biosphere’s going to “restore itself” within, you know, 10 million years. Whatever. That’s fine. And we — you know, some form of humanity — may be part of that, or may not. But the reality is that what we want to do, as human beings, is we want to tip the odds in our favor a little bit. We want to increase the odds that we’re going to be one of those lucky species that survives. And we know enough to be able to do that. We know now enough about evolution to be able to alter our behavior in a way that’s going to increase the odds that we’ll survive. So the question is, are we going to do that? So this whole business of whether or not, you know, what’s going to happen in 3 million years — you’re right: That’s not important. But what happens tomorrow is not important either. What’s important is what happens in the first generation after 2050. That’s what’s important. That first generation after 2050 is going to determine whether or not technological humanity reemerges from an eclipse, or whether Homo sapiens becomes just another marginal primate species.
