     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'".

     Reacting to the launch of the prize, Tony Jupiter, the Friends of the Earth's director, warned against

wasting time waiting for new inventions.He said, "Sir Richard's initiative (初衷) may encourage inventors

to develop a wonder technology to deal with carbon dioxide of the atmosphere.But many of the ways,

such as energy efficiency and renewables, already exist, and it is essential that these be put into practice

as soon as possible.Moreover, Sir Richard must also look at his business activities and the contribution

they make to climate change.The world will find it very difficult to settle climate change if air travel

continues to expand and space tourism is developed."
