Jennifer Aniston has a novel way to save the environment - she brushes her teeth in the shower. The actress revealed her eco-friendly tip on the eve of Al Gore's Live Earth concerts on Saturday.

She says, "I take a three-minute shower. I even brush-wash - brush my teeth while I shower. Every two minutes in the shower uses as much water as a person in Africa uses for everything in their life for a whole day."

The 24-hour Live Earth concert begins in Sydney, Australia and continue across the world with events in Japan, China, South Africa, Germany, London and Brazil, before concluding in New York.
