What your point is or how it relates to what I said, I have no idea.While it is true we could resolve issues through killing each other in many ways that’s just a different market - a market of violence.
The link I presented has nothing to do with this yet you and others harp on it endlessly.Assuming the link is correct, "Without engaging with natural environments, our brains cease to work well. As the new field of environmental neuroscience proves, exposure to nature isn’t a luxury – it’s a necessity", it doesn't matter a fig how much natural environment there is if you are not connected to it.So density preserves nature.
When I was a child I could ride my bike and be lost in the wild nobody having the slightest idea where I was. I explored abandoned buildings, massive gun turret, caves and miles of ocean shore. I found a fossilized whale in a cliff next to my school. I caught snakes and lizards and horned toads, ant lions, ants, pollywogs and frogs. I could lay on grass and watch the clouds float by. There were fruit trees and berries planted by my parents in the yard. I can smell the white sheets my Mother would hang to dry in the yard. I remember two black men teaching me when I was 4 or 5 how to suck nectar from a honeysuckle flower. I didn't have to go anywhere couldn't manage myself.
