Watch: Environmental Innovation, Courtesy of TED

Ever heard of TED? No, not Bundy or Kennedy, we're talking Technology, Entertainment, Design, better known as TED, a nonprofit dedicated to what its founders call "ideas worth spreading." Its biannual conferences bring together "the world's most fascinating thinkers and doers," producing some amazingly creative ideas. Fortunately for us, TED makes its very engaging lecture footage available online.

Environmentalism, not surprisingly, is a hot topic at TED. We enjoyed the above video, in which photojournalist Brian Skerry explains how his experience photographing ocean creatures inspired him to tell conservation stories.

Check out some of the other fascinating clips, too, like the one of Bill Gates speaking about our energy future, or the one in which accomplished architectural researcher Rachel Armstrong discusses her ideas for buildings that repair themselves while also sequestering carbon. At 16 to 18 minutes each, the videos are a bit longer than is typical for the web, but they're well worth watching.
