>>8There are people in every generation who warn of apocalypse and cataclysm. The only difference now is it's based on eco bullshittery and bad science instead of religion. History is filled with people saying the world was going to end ("global warming" "resource exhaustion" "peak oil") unless everyone atoned for their sins ("stop polluting" "stop reproducing" "stop using plastic straws").
You will die one day, and the world and billions of people will still be here. Just like all the doomsayers before you.
