  • Going a couple comments up the chain:

    Even if humans manage to kill off most life on Earth it will continue to exist, propagate, and become more complex. Again we’re talking about billions of years. There have been huge shifts in climate and mass extinctions many times before and yet here we are.

    So I took it to mean all life on Earth being dead. As long as one microbe survives to reproduce and start evolving it doesn’t count.


  • 75% of all species, not all life. Larger species and photosynthesizers were more heavily affected, while smaller species, scavengers, and deep sea life were less affected.

    And I’m not a biologist, but I’m pretty sure even 75% of all life, not species, still wouldn’t be close to completely ending life on Earth, cause in the end as long as some microbes survived around a hydrothermal vent somewhere total extinction would be avoided.


  • Eh I doubt it. Every single nuke ever built combined still doesn’t come close to the power of the Chicxulub asteroid (the one that killed the dinosaurs) and even that impact didn’t come close to eliminating all life on Earth. Unless someone accidentally compresses a mountain into an artifical black hole or something there probably is no way to wipe out all life on Earth.
