I regularly listen to the podcast of Science Friday a weekly show on NPR about science related topics. There was one recently called Brown's 'Plan B 3.0' an Environmental Call to Action which is an interview with Lester Brown, an environmental analyst from the Earth Policy Institute. Plan B 3.0 is Brown's latest book about his "plan to save the planet from climate change. But with calls for a carbon tax and more gasoline taxes, it's not going to be easy or cheap". The quote was from the shownotes.
The interview itself is an excellent listen with topics ranging from carbon taxation, wind power and, my brother's favorite, bottled water.
Even better, the entire contents of the book are available on the Earth Policy Institute website for free.
