On this episode we take a look at the role technology plays in conservation efforts. First we speak with Topher White of Rainforest Connection, which deploys used cell phones in tropical forests around the world to provide real-time monitoring of forests and wildlife. Its network alerts local communities when illegal logging activities are taking place and can then be stopped, for example.

Then we speak with Matthew Putman, he's the CEO of Nanotronics and an applied physicist with a keen interest in conservation. We discuss some of the technologies that he sees making the biggest contributions to the way we approach conservation, and why he believes these advances can help turn the tide against environmental degradation.

Plus we round up the past weeks' top news.
