You see celebs blowing up buildings on TV and they rarely recycle in the movies, but in their personal lives, many celebrities are actively lowering their ecological footprint and are doing their part to take care of the environment. A few of these celebrities can be read about in Treehugger's Culture and Celebrity category, and you'll meet some of these famous conservationists on G Word, but until then, below are but a few tales of Hollywood heroes and heroines gone green.
