Capitalists do not destroy the environment because of malice, no one wakes up one day and decides they really wanna fuck up some coral or drive a species of frog to extinction

Capitalists destroy the environment because of a specific profit imperative that dominates their thinking and behavior, profits go up when costs go down, and the maintenance of the environment is an external cost

So the snuggly or non-snuggly nature of humans prior to capitalism is completely irrelevant
