Sure, celebrities live the good life: Limo rides, fancy clothes, swanky dinners, million-dollar mansions.
You name it, they can probably have it.
But even if they live the lifestyles of the rich and famous, some stars remain aware of our planet's ecological issues, and are willing to help improve the planet in a variety of different ways. Brad Pitt famously threw on a hard hat to help New Orleans by building eco-friendly homes. Hayden Panettiere works to protect the lives and habitats of dolphins and whales. Leonardo DiCaprio does enough good stuff that he gets officially recognized for it—along with Matt Damon.
They aren't the only ones. But they are among the people using their fame for more than just a good table in a restaurant, and that's a good thing.
So check out some of the stars doing good things, and sound off in the comments about the issues that matter to you and what you're doing about them, too.
