Natalie Coughlin, swimming
This California native earned multiple medals — including gold — in the 2004 and 2008 Olympic Games. She has won 11 Olympic medals, and she left the 2004 and 2008 Olympics as the most decorated female athlete of the Games. (That means she’s won a medal in every Olympics she has participated in.) How does she keep it green? “I eat seasonally and compost,” Coughlin shares. “I also grow organic veggies, saving seeds year to year."
