Sydney in Australia is set to be the first city to stage a Live Earth concert, a global event intended to raise awareness of climate change. Eight other cities, including London and Washington, are holding gigs. Among the biggest names performing live are Madonna, Red Hot Chili Peppers, Metallica, The Police and Garth Brooks.
Microsoft, the exclusive online media sponsor for Live Earth, has launched the MSN Live Earth Tree - an interactive online animation that lets people worldwide pledge their commitment to the environment and join the battle to halt climate change. The Live Earth Tree invites users to visit the site to design their own unique leaf for the tree, and pledge to make small lifestyle changes to reduce their impact on the environment.
