Environmentally friendly Leo is certainly committed to making the world a better place. He started an eponymous Foundation to raise environmental awareness and he's financially supporting a child in Africa. He chooses to work on films that educate and inform such as Blood Diamond and the upcoming Conspiracy of Fools, about political corruption. As if that weren't enough, he's produced and narrated a documentary out this year called 11th Hour which also deals with environmental issues. All this and he's about to get into a Prius. Maybe next time he will remember to wear a coat in cold NYC since he has to probably pump up the heat in the car.
