Daniel Goleman has followed up his previous bestsellers, Emotional Intelligence and Social Intelligence, with a new one -- Ecological Intelligence: How Knowing the Hidden Impacts of What We Buy Can Change Everything. Ecological intelligence is a way for us to avert environmental catastrophe, and it depends on our knowing whether products are truly environmentally friendly or not. These days many products look "green" -- or they're marketed that way -- but when you scratch the surface, you realize that these new products are often more damaging than the "non-green" products they're meant to replace. This week, Goleman was interviewed by Bill Moyers. With this 17 minute video, you'll get a quick introduction to what "ecological intelligence" means, and how you can become a smarter consumer. Along the way, Goleman recommends two handy web sites that will let you assess the environmental friendliness of products. One is called GoodGuide (which is also available as a free iPhone app). The other is SkinDeep.
