One Man's Swamp is Another's Green Infrastructure

摘要

I once received a phone call from a woman who was very upset by a "nasty swamp" that she passed every day on her way to work. The swamp collected all sorts of trash and garbage every time it rained. While the city made some effort to clean up the trash periodically, she couldn't understand why they didn't just drain the swamp, fill it in and turn the land into a park or something useful.
