I love to shop at thrift stores, which is like recycling! It's also cheaper and fun. You're going to be wearing something that nobody else has." 02 of 11 Aubrey Plaza Jason Merritt/Getty Images "I'm pretty good about not drinking bottled water. When I'm working on Parks and Recreation, we all have thermoses so that there's not so much waste." 03 of 11 Garcelle Beauvais Lionel Hahn/AbacaUSA/startraksphoto.com "We're changing all our lightbulbs out at our house. I taught my children not to leave a light on when they're not in the room." 04 of 11 Benedict Cumberbatch Anthony Behar/Sipa USA "I walk, I cycle, and I take public transportation.
