We kill 80 billion land animals per year for factory farming and we’ve caused almost 2 species of animal per year, every year, to go completely extinct over the last 500 years.

We are going to destroy almost all life on this planet.

Even if we intentionally released as much co2 as we could all life on earth is not at risk. Remember that there's a fair amount of life that is virtually unchanged since the paleozoic period when all that co2 was in the air. Beyond that there's stuff that hangs out in volcanic vents, rapidly evolving life that can adapt even to rapid change, bacteria, molds, mosses and algae. And who knows maybe there's even a small adaptable mammal or 2 that gets out and evolves enough for a second attempt at sapience.

Don't get me wrong the climate disaster is truly a unique and devastating extinction event, but humans are not so powerful as to leave the earth a completely lifeless rock.

Exactly. Fuck the humans, at this point I just want as much as else possible to be saved.
