“I cannot not be green,” Watson told a French magazine. “I did my end-of-school project on global warming and Hurricane Katrina. … My car is electric, I recycle, I take public transportation, I try not to buy and drink bottled water. I’m not perfect, but it’s something I feel strongly about.” The interview inspired Greenpeace to ask her to serve as a global ambassador (no word yet on her response). She even donated to the Wild Trout Trust. Witch enviro cause will be next?
