Anti-Blackness & Anti-Darkness
The deep ignorance of spirituality that colonial europeans spread across the world is the most tragic effect of the mess they've made, in my opinion.
Their lack of interconnectedness with the Earth, fierce individualism, and fundamentally flawed, restrictive, one-sided religions drove (and drive) them to carry out the greatest horrors this Earth has ever known. If you ask me, the euro-centric worldview lacks the basic reverence for life-energy that almost all non-european groups understand.
I don't really care much about "why" it happened, evolutionarily. Like yes, Europe was cold, lacked resources. Maybe they were forced into a survival state that cut them off from the possible souls they had. Maybe they resent the Earth for seemingly not giving them what they needed to thrive in their indigenous environments. Sure, fine, all of that.
But they're not in the tundra now, and are still deciding to dominate or behead everything in sight.
Even though they technically are of the Earth, I consider the european influence on the Earth to be something unnatural; to be corrected.
