There have already been multiple mass extinctions in the past driven by global climate shift. There are currently 1 million species at risk of extinction right now, which is a significant fraction of known species. Full on ecological collapse has been happening on all fronts for years, and it still continues to accelerate. "society" isnt responsible for pollinating plants or turning co2 into o2, and it's scary how ea…
