Humans are nature and the entire planet is our home, which must be maintained regularly. This idea that we need to separate ourselves from the so-called natural world in order to protect it seems incorrect based on history. Many indigenous groups maintained thriving forests, grasslands, etc for centuries before colonizers showed up. Many other animals maintain their environments as well; beavers, elephants, etc. Humans are pollinators too!

Obviously we do many horrible things to our environment, but that's not an innate human behavior. We learned to be destructive of our own environment over time and then it was spread everywhere through colonization. Many people went from being just another animal to seeing themselves as special and, largely through religion (not saying religion is bad, just saying it was used as a tool by the ruling class to indoctrinate people), were taught that everything and everyone existed to be exploited for resources. Capitalism is born out of this idea that we are not part of nature.

I think alienation as described by Marx and others after him explains what I'm saying here in a different context and certainly in more detail. I also don't think we shouldn't mostly live in cities of some type, but we absolutely need people out in the world taking care of it. Moreover, I think at least a not insignificant number of humans simply cannot thrive in dense urban environments.
