Eating organic is all the rage these days - but could it actually help save the planet from climate devastation? As the reality of global climate change continues to sink in - scientists - activists - and lawmakers all across the world are working to find new ways to fight back against greenhouse gas emissions before it's too late. Thom's guest for tonight's Conversations With Great Minds - Tom Newmark - is one such person. A former corporate attorney turned organic farmer - Tom is now at the forefront of the movement to use agriculture to fight global warming. He is the co-founder of the new non-profit the Carbon Underground as well as the co-owner of Finca Luena Nueva - an organic farm in Costa Rica. Tom is also the co-founder of Sacred Seeds - a trustee of the American Botanical Council.
