Green Hands USA: America Volunteers

Just a few short weeks from now, people around the world will turn off their lights for one hour to show their support in the fight against climate change.

The Earth Hour event takes place Saturday, March 26th, and encourages everyone who signs up to turn off every light in their homes from 8:30-9:30 pm (local time).

Earth Hour started four years ago, when 2.2 million people participated. Last year, 128 countries participated. This year promises to be even bigger.

The Earth Hour event goes beyond individual acts and encourages you to tell your friends and influence your community. Think you can get local stores and government offices to turn off their lights on March 26, too? Then go ahead and do it! There are also all kinds of downloads to help promote events on a corporate and community level.

So if you'd like to send a message about our impact on the planet and climate change, go ahead and sign up for this year's Earth Hour. You never know how much change you can create on your own until you try.
