This is both biography and a philosophy about finding uses for old things. An everyday sanitation worker in New York City collected things that were broken, but could be fixed could be reused, could be reimagined. He turned his treasures into a museum. His idea was to show people that what one person thinks is trash, could be treasure because he grew up with the lesson that all things are used until there is no use left. This was a lovely story that I think kids will get behind whether an environmentalist or not.
