Oh gosh. The two eternal hazards of my childhood (that my parents would yell at me about) were dog shit and broken glass. I distinctly remember going to a school playground when I was about 6, and wanted to crawl through a plastic tunnel, but didn't when I saw a huge pile of shit in the middle.
Now, pooper scooper laws took care of the former, but people still get drunk off their ass and leave bottles everywhere.
I am not sure this is true, isn't it that potential for damage to the enviroment (beyond only simple trash) increases with the economic power of the nation and therefore preservation would have to track economic progress?
I would think that preservation efforts would have track economic progress, but the effects lag in time and therefore gets noticed too late and costly renaturation efforts need to happen.
My wife, who is originally from Indonesia, always notices the same thing in The Netherlands. The contrast couldn't be bigger. She also has these feelings of sadness and shame.
