EAST RUTHERFORD, N.J. (AP) - In a 24-hour music marathon spanning seven continents, rock stars sharing the spotlight with aboriginal elders and famous scientists urged their fans to turn interest in the Live Earth events into environmental activism.
"Put all of this energy in your heart and help us solve the climate crisis," said former Vice President Al Gore, appearing onstage at the end of the final concert, staged at Giants Stadium in New Jersey.
With other shows in London, Sydney, Tokyo, Kyoto, Shanghai, Hamburg, Johannesburg, Rio de Janeiro - and even a performance by a band of scientists at a research station in Antarctica - organizers called Live Earth the biggest musical event ever staged, dwarfing the Live Aid and Live 8 concerts.
Live Earth venues featured aboriginal elders, chimpanzee calls from scientist Jane Goodall, a holographic Gore and more than 100 of the biggest names in music - including Bon Jovi, Smashing Pumpkins and The Police.
The concerts were backed by Gore, whose campaign to force global warming onto the international political stage inspired the event.
Musicians and celebrities at each show encouraged fans to take little steps, such as not leaving electrical devices plugged in when not in use and changing to low-energy light bulbs.
The Police, led by frontman Sting - who along with his wife, Trudie Styler, has been active on environmental issues for years - was the last act to perform in the global concert series.
They were joined on stage by John Mayer and Kanye West for a version of "Message in a Bottle."
