Thread backfire!
Building up allows for more space for nature, not less.
Which misses the point, which is being surrounded by it, not hypothetically having some kind of access to it after traveling there as some kind of token gesture of "access".
Sucks to be in such a bad environment that you don't understand the difference.
I have trees, a field, a pond, ducks, geese, horses, foxes, coyotes, hawks, buzzards, owls, squirrels, rabbits. Walking to some populated public park that's just a bunch of grass, bushes and trees (and hookers/pedos/homeless/drug-addicts/etc) replaces that? lol, you have no idea.
The park is not "nature" and if you have to travel to it, even by foot, it's a complete DOUBLE-fail.
Higher density living sucks because there are always a few % among them that are jackarses and disrespectful of others. You can maybe get those jokers out but then more move in. The basic peace that many people enjoy 24/7, is hit or miss, not sustainable.
I get it, living in a busy area is exciting for young people, but then as they experience life, practically nobody past a certain age/ wisdom level, decides to move from a less dense area into a dense area unless their job requires it. It's quite the opposite.
Dense living is for the young till they wise up or for the poor. It is a downgrade in quality of life otherwise. That does not mean, live out in the wilderness where access to merchants and services are hindered. There is a middle ground.
Housing density increases can make for more efficiency but at the expense of everyone in them, unless they are mentally blocked from owning a form of transportation and feel proud that they are handicapped by walking everywhere because they don't want to own/drive a vehicle. If it makes them feel happy, that's what matters though this is largely an illusion for people in good health that don't realize, things go downhill as you age, and the extra burden from bad choices, adds up over time.
A denser population is just more suffering for the average inhabitant, unless they are a vegetable who depends on services because they can't fend for themselves for basic needs. This excludes the young kids out there that want to breed and meet as many people as possible to choose the right mate, but then if they are wise, after meeting that mate, will move into a less dense area.
Long story short, what do the richest people choose? If money is no object, do they choose to be squashed into dense living? No. Many of the replies to this topic, ignore the obviousness of this. Even so, do whatever makes you happy. Choice is a good thing.
