Can literally any day to day activity that distracts you from the existential dread that arises from thinking about the overwhelming ecological complexity and insane amount of political and societal momentum necessary to curtail the worse effects of the climate change?
Yes...yes it can.
Is it bad for the environment to very slowly cook a GPU to distract you from the coming climate catastrophes? Yes. Is it good for your mental health?
Ehh...maybe...but most of us are just partying at the end of the world cuz we might as well get ours (aka live a full life) while the very young get angry about how they never got theirs (aka lived a full life).
