TreeHugger Radio: High-Tech Yurts, Satellite Seals, and The 11th Hour

This week we take a look at the new film The 11th Hour, the local focus of this year’s Farm Aid concert, and some oceanographic temperature-taking done with the help of seals. We also talk to Vinay Gupta, the creator of the Hexayurt, a portable survival structure for refugees. Subscribe to TreeHugger Radio on iTunes or listen/right click to download. ::TreeHugger Radio
