I agree with the part about people who worry about everything. But the bit Carlin misses is that what's troubling is the increase in the rate of extinctions[0]. Of course species go extinct on a regular basis, but when so many are going extinct in such a short space of time, it creates issues like a reduction in biodiversity, which in turn leads to a higher risk of a disease outbreak in a dominant species being catastrophic for an ecosystem. I agree with Carlin about most things, but like Bill Hick's blind spot about smoking, I think he's wrong here.
