Global warming is probably a problem (and possibly a severe* one?) but its not anything remotely near an existential risk.
As far as I can tell, there are basically three human caused scenarios that could maybe lead to human extinction (not counting technical extinction via transhumanism)- UFAI, world war with WMDs (I’m not sure if today’s nuclear arsenals can accomplish this?), or some kind of synthetic super-pathogen. UFAI would kill “Mother Nature” dead too.
That caring about people over “nature” is labelled “self centered” with negative connotations really highlights why I despise environmentalism though. (IDK if that’s the intentions of the artist, this might just be cosmic horror, but I’ve encountered that attitude a lot)
*the scale/scope is a bit wonky when labeling worldwide problems by severity

THESEUS ARMED FOR WAR AGAINST THE GODDESS OF CANCER AND THE GODDESS OF EVERYTHING ELSE.
If you meet Gaia, mock the “selfishness” of her apparent desire that so many ecosystems and species thrive. It is an appropriate response to the assertion that a desire for 7 billion happy and prosperous humans is selfish.
