Each year, the TED (Technology, Entertainment, Design) Conference invites experts from a variety of fields to share their knowledge in 18 minute lectures. Jamais Cascio gave this talk back in February of 2006 discussing solutions for a sustainable future. He talks about the need for optimism and how, “focusing only on negative outcomes can really blind you to the very possibility of success.” He emphasizes staying positive, citing scientific and technological advances that help us better understand our impact on the world around us and how to lower that impact.
He even touches on the power of social networking! The Earth Witness project he describes sounds like a really exciting idea – one that might be doable using a microblogging service like Twitter that allows folks to send texts straight from their cell phones to the web!

Who knew that something as simple as a cell phone could be an instrument for social change?
This year’s TED Talks are going on right now in California! It’s their 25th anniversary, and they have some amazing speakers lined up. I can’t wait to see what inspiring talks they publish this from year’s conference!
