First of all, we are a product of it. We also demand nutrition, like any other animal. We work by the same principles like any other animal. We just have a large neocortex, which allows us to solve complex problems, which other animals cannot. We use this to our advantage like any other animal would do. I am not saying that it is the right thing we are doing but we grew out of primitivism and have much more complex problems at hand now, which mainly need us to reject our tribal behaviour and move past it. Many of these large problems are due to our tribalism. Why should we care about the world? We care about our loved ones only. Why should I give money to people I do not know? I would rather give it to my close ones. Everything else is a potential threat. Our tribalism doesn’t function properly at this scale and we have to move past it somehow, while it is deeply natural for us to behave like this and it’s at small scale also beneficial and not harmful to others.
