Nature-lovin’ nations around the world planted more than 1 billion trees during 2007, meeting a kinda arbitrary goal set by the U.N. last November. The effort, boosted by Ethiopia’s planting of 700 million trees, “is a further sign of the breathtaking momentum witnessed this year on the challenge for this generation — climate change,” said Achim Steiner, head of the U.N. Environment Program. And speaking of breathtaking momentum, Indonesia announced today that it will plant 79 million trees in time for the kick-off of the Bali climate conference — on Monday. Oh, our achin’ backs.
