Video: Alex Steffen on Bright Green Cities
In his July 2005 TED talk, "Inspired ideas for a sustainable future", Worldchanging.com founder Alex Steffen offers a still relevant, lightning round of answers, to some of our planet's greatest sustainability challenges. Its a wide perspective on topics which range from real estate development (green cities and buildings), to digital collaboration tools, to ingenious tools for the developing world. At his site, which he calls a "news service for the unimaginable future", Mr. Stefen states that "plenty of people are working on tools for change, but the fields in which they work remain unconnected. That the motive, means and opportunity for profound positive change are already present." It is a showcase for inspired ideas that can contribute to a greener future and a more stable planet.
