> And given that biodiversity is what got us to where we are Mass extinctions also is what got us to where we are. If dinosaurs were still around when humans started to evolve, it might have been a Bad Thing. Many species are supposed to go extinct, all the time. That's is how nature and evolution works. If we become extinct, then it paves the way for human++. This is neither good nor bad, it's just how life has evolved for billions of years. I think if we try to stop this and maintain status quo, that is ethically and morally wrong. |

True, but what are called "mass extinction events" actually took place over tens of thousands of years, which is "quick" when talking about geological time. We're potentially talking about a mass extinction event taking place over hundreds of years. The problem is that's a long time compared to a human lifespan, but an extremely short time from a geological standpoint. We have nothing from the past to analyze what the effects of this exceedingly fast extinction event will be - including whether it will lead to such ecological collapse that complex land animals such as humans can continue to exist. We simply don't know. One would think we should proceed with caution, but instead we're hitting the accelerator.
