At what scale do you want it? Your neighborhood? Town? State? Continent? Planet?

My understanding is that it is the kind of thing that needs to be supported from the bottom up.

I probably prefer a clear separation of nature and non-nature, with my home/backyard being the latter one, but having actual nature within a walking distance - which requires the non-nature parts to be dense, not sprawling wide.

Your NIMBYism sounds like the typical response to diversity, bio or otherwise. Try replacing "nature" with some other terms; it's not a flattering statement.

Nature preservation should come top to bottom in the form of regulation

Bottom up doesn't work and doesn't scale.
