Happy Earth Day!
It's Earth Day 2011–a day for everyone, not just environmentalists, to think about the climate and take action! This year's theme is "A Billion Acts of Green." Earth Day organizers want the world to generate a billion acts of service to our environment before the Rio +20 UN climate conference in June 2012.
What are you doing to celebrate Earth Day? And will you take part in an "act of green?" Share your stories with us!
