Humans absolutely created prosperity. The thing that was already here was nomadic hunter gatherer tribes that were perpetually one bad winter away from death.
Cutting off necessary resources is cruel. But refusing to acknowledge that those resources are provided by man made systems doesn’t help you. Going to bed hungry is very natural. Wild animals do that all the time. Tap water is not natural, everything about how that water got from the river into your tap was man made.
Just because it’s natural doesn’t mean it’s better, and just because it’s man made doesn’t mean it’s bad.
Shit, I remember these in school. And I’m 22, pretty sure early 20s isn’t ood enough to count for an “are you this old” meme.
