2 claims in “urban planning”
The US has over 2,600 overflowing landfills and hundreds of declining malls, suggesting that a solution could be to locate second-hand retail centers (like Riatuna) next to landfills and recycling centers in declining mall locations.
Population decline may create opportunities for more attractive living arrangements—cities can be abandoned and people can concentrate in more beautiful places like New York or San Francisco, potentially improving quality of life.
