MSN launched the "Live Earth tree" public welfare activity

Microsoft has set up an environmental promotion site in Live Earth, using interactive online animations to remind people to protect the environment and stop climate change.

On this page, you are free to draw a leaf and stick it to the tree on the page, adding green to the tree, which at the time of writing is already lush :)

The drawing of each leaf will be recorded, and everyone's drawing of the leaf can be reviewed and played back, very fun!
