Society: National Geographic's Garcia discusses new index tracking consumer action on climate

Where do U.S. consumers rank compared to the rest of the world in terms of environmentally conscious choices and habits? During today's OnPoint, Terry Garcia, executive vice president of mission programs at National Geographic, discusses the "Greendex 2008" that ranks the environmental habits of consumers in 14 countries. Garcia explains why Chinese consumers are among the most concerned about the effects of global warming and he discusses the factors contributing to the United States' last place ranking. He also explains the differences between consumer attitudes in developed and developing countries. Garcia addresses how governments should use the information provided in the index to help shape environmental policies.
