Live Earth Kicks off this Weekend
Live Earth is a 24-hour, 7-continent concert series taking place on 7/7/07 that will bring together more than 100 music artists and 2 billion people to trigger a global movement to solve the climate crisis.
Live Earth will reach this worldwide audience through an unprecedented global media architecture covering all media platforms - TV, radio, Internet and wireless channels.
Live Earth marks the beginning of a multi-year campaign led by the Alliance for Climate Protection, The Climate Group and other international organizations to drive individuals, corporations and governments to take action to solve global warming. Former U.S. Vice President Al Gore is the Chair of the Alliance and Partner of Live Earth.
