This concert is part of a series of events, also taking place in the U.S., Australia, China, Japan, Brazil, South Africa and Antarctica. Live Earth was inspired and is backed by by former U.S. Vice President Al Gore's campaign to force global warming onto the international political agenda by generating public concern.
