GRITtv: September 23, 2009

Nobel Peace Prize Laureate Wangari Maathai, founder of the Green Belt Movement, is on Grittv today. She says that all countries, industrialized and developing, must learn to live within their means. Maathai was in New York for the UN summit on climate change, which she addressed yesterday. Speaking of pledges and promises, what remains of the public option? Will it survive? Maggie Mahar, author of "Money-Driven Medicine," offers opinions and suggestions.
