Today is the 40th anniversary of Earth Day. Across America, communities honor our environmental holiday by raising awareness about green issues and working to make a difference at a local level.
HuffPost Impact is highlighting the ways Americans are getting involved on Earth Day -- and letting you know how you can join in. You can also celebrate Earth Day by going to see Disneynature's new film Oceans -- for every person that goes to see the film in its opening week, a donation will be made to The Nature Conservancy.
