　　Sir Richard Branson today offered a $25,000,000 prize for scientists who find a way to save the planet from the effects of climate change.

　　Supported by the former US vice­president Al Gore and other environmentalists, the boss of Virgin Atlantic airlines called for scientists to come up with a way to take greenhouse gases out of the atmosphere.

　　“What we are doing is making sure we get the most carbon dioxide­friendly planets.We promise that 100% of profits we make from our transportation business are put into things like the prize we've offered today.We shall convince people that we are facing a threat which is urgent and there's no superhero.We have no hope of a meaningful solution unless we find a way to work together.”he said.

　　Mr Gore said global warming was man­made and was like the planet suffering from a“fever”．He said，“Humans had slipped into a way of thinking that was centered on‘short term satisfaction', and now meet the challenge of ‘transforming ourselves and changing the structures of everything we do'”．
