It sounds like a weird riddle: What do a bicycle, clothesline, library book, "real" tomato, ceiling fan, microchip and condom all have in common?
My friend and former competitor Eric Sorenson answers the question in a new book he wrote along with the staff of the Sightline Institute entitled "Seven Wonders For a Cool Planet: Everyday Things to Help Solve Global Warming."
The basic idea is that while we have some huge challenges, particuarly related to climate change, we also have some pretty effective technology to deal with those problems. So it's really about transportation, population, energy efficiency, renewable energy, our food supply, resource conservation (the library book) and the information economy. (May 2, 2008)
