LEONARDO DICAPRIO

"A consensus has emerged in our scientific community that global warming is no longer merely a theory but a reality, a crisis with truly global implications for planet Earth and all of us who share it," DiCaprio told the thousands at the New Jersey concert for Live Earth this summer – just one of his many high-profile gigs as an environmental activist. Since 1998, his Leonardo DiCaprio Foundation has awarded millions of dollars in grants worldwide for eco-friendly causes, and most recently co-produced the climate change film The 11th Hour, which DiCaprio himself narrated.
