Leonardo DiCaprio is a die-hard environmentalist who is the proud owner of his electric Tesla Roadster, Fisker Karma plug-in hybrid and Toyota Prius. If that doesn’t say enough about how he chooses to support the economy, you may be happy to know that he has taken the step to also install solar panels on his house. In 2010 DiCaprio donated 1$million to the Wildlife Conservation Society at Russia’s tiger summit and joined the Animal legal Defense Fund’s campaign. When he spoke about global warming in 2014, he cited that it was the “number-one environmental challenge in the world today.” More recently, DiCaprio donated 2$ million to Oceans 5 to improve the health of our oceans. He also marched in NYC for action on climate change as well as receiving the Clinton Global Citizen Award last year. Leo does as much as he can to help to ensure a healthy future for humanity and the planet as a sustainable hero!
