Earth Day 2010: The Best Ways To Get Involved

Forty years after the first Earth Day, the world is in greater peril than ever. While climate change is the greatest challenge of our time, it also presents the greatest opportunity – an unprecedented opportunity to build a healthy, prosperous, clean energy economy now and for the future.
Earth Day 2010 can be a turning point to advance climate policy, energy efficiency, renewable energy and green jobs. Earth Day Network is galvanizing millions who make personal commitments to sustainability. Earth Day 2010 is a pivotal opportunity for individuals, corporations and governments to join together and create a global green economy. Join the more than one billion people in 190 countries that are taking action for Earth Day.
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.

The world's coral reefs are threatened due to global climate change, overfishing and pollution. The Nature Conservancy gives individuals an opportunity to adopt a coral reef in the Bahamas to help fund their ongoing work to protect these ocean ecosystems.
