Today is Earth Day, but for some stars celebrating and protecting the planet is a year-round endeavor.
A number of eco-conscious celebrities have joined Earth Day Network’s Billion Acts of Green campaign, which encourages people (famous and unknown) to do what they can to help the environment.
According to Earth Day Network, more than 100 million pledges have been “committed” since the campaign kicked off on last year’s Earth Day. Here are what some of the stars have done:
Leonardo DiCaprio recently pledged $1 million to World Wildlife Fund for tiger conservation, and teamed up with the organization to launch www.SaveTigersNow.org.
– Edward Norton ran the New York City Marathon with a team of Maasai warriors in support of the Maasai Wilderness Conservation Trust, raising over $1 million through his online fund raising website, Crowdrise.com.
– Ian Somerhalder created the IS Foundation to educate and collaborate with people and projects to positively impact the planet and its creatures. The organization recently collaborated with Conservation International to save over 300 acres of forest.
– Sienna Miller visited India as an ambassador for Global Cool to help raise awareness among the people of India about the harmful effects of global warming.
