The Demands of Resources for Limited Things

The OECD talks about the demands of resources for limited things. What are places you've been to where you felt it was a bit ruined by the crowd? I went to Big Sur and there were so many people walking on the trails in the forest that it made the forest not able to be walked upon. And another case is two years ago, my wife and I went to Yellowstone and we'd been there 10 years ago. The geysers were literally filled with hats and umbrellas. You could walk across them just stepping on the hats.
