not even all life. i’m sure some microbe or spore will survive long enough past human extenction and life will flourish once again. there are some very robust little lifeforms out there, living in boiling volcanic water or surviving frozen in permafrost. i’m sure some can manage in high CO2 levels and hot climate.
Life existed long before there were any significant levels of oxygen in the air. I doubt humans can undo much of the ~20% oxygen level that exists today. And I think that’s reason enough that life even bigger than microbes won’t die out.
