On Mar. 27, 2010, people around the world are expected to join in a one-hour rally against climate change -- Earth Hour. For an hour starting at 8:30 pm, they will refrain from using electricity.
Participating organizations will shut their power to remind the world to conserve electricity. Before that, participants can join a free one-hour yoga session in the park... Earth Hour is organized by the Swiss-based non-profit environmental organization, World Wide Fund For Nature.
