Having natural spaces within communities is vital for mental health. For example, Central Park in NYC is a vital resource for the city allowing people to enjoy nature close to home. Kids need places to go and play. Adults need space to recreate. Pets need space too. Why would you want to have no green spaces within your community?
It's farm land. Sounds pretty wild to me. Also, we have wild land set up as parks as in national/state parks. A park doesn't have to mean slides/swings and a bunch of ankle biters running around.
Because people want/need accessible parks? Texas in particular has relatively very little parkland compared to its size, and its population-to-park ratio is getting increasingly out of whack
It just depends on the size. I know of several 1000+ acre parks that would be essentially considered wild areas with the exception of a few hiking paths.
They are full of wildlife ranging from small rodents to bears.
