We have discussed global warming and how we can reduce our carbon footprint several times on this show but we generally focused on the debate about whether climate change is real and man-made. Our guest today, film director Peter Byck, decided to forget the debate. He simply traveled the country to meet people who were actively reducing their carbon footprint whether they believed in global warming or not. These people just think it's smarter to use less energy or to create it more efficiently. Byck sees these innovators and entrepreneurs as part of Carbon Nation and he made a film by the same name. He'll join us when Charlotte Talks.
