In honor of Earth Day, we present the top five celebrities who use their fame to help make the earth a better place to live.

Our number one: Leonardo DiCaprio

The Vanity Fair green issue cover model and hybrid driver created the Leonardo DiCaprio Foundation in 1998. He makes every effort to generate awareness of environmental issues, partnering with organizations that include Natural Resources Defense Council, Global Green USA, and the International Fund For Animal Welfare.

Check out the gallery to learn more about Leo's great efforts and see who else made our list of Eco Celebs.

Being fashion-forward doesn't mean you can't sport eco-friendly duds, too. Adding a few sustainably made items here and there is a great start, but what if you're ready to really do an overhaul? There are so many choices -- where do you shop? And what should you do with your old clothes?

Not to worry! You can hire your very own EcoStylist at Coco's Shoppe!

A lot of designers take the position that fashion is all about looks and nothing about ethics. That's how we get things like the bacon bra -- where could you possibly find a less eco-friendly piece of underwear? If you're willing to get intimate with the problems that face our planet, you can start by exchanging your old-school undies for some eco-friendly underpants.

Rapanui makes ethical cotton underwear for men and women. They're a bit on the basic side, but simple is beautiful. The breathable, hypo-allergenic cotton is grown on reclaimed commercial farms where Rapanui works to remove all chemical deposits from the previous owners' operations. This soft fabric is not only gentle on you skin, but also on environment -- since it's factories are powered by wind and solar energy. Rapanui also imposes a 5% eco-tax on itself that it puts towards other environmental causes and organizations.
