Why be optimistic? Larry Brilliant at Skoll World Forum, on TED.com

skolllogo.gifRecorded at the Skoll World Forum on Social Entrepreneurship, Oxford, UK: 2006 TED Prize winner and Google.org director Larry Brilliant uses a clip from an old Frank Capra movie to show that we’ve known about global warming for 50 years — yet in half a century, we’ve done almost nothing to solve it. He explores this and other megatrends that could inspire pessimism. But, he says, there is a more powerful case for optimism. (Recorded March 2007 in Oxford, UK. Duration: 21:01.)

The Skoll World Forum on Social Entrepreneurship in Oxford, UK, is an annual gathering of innovators from all over the world who are creating positive change across critical issue areas.
