(Apologees to Jim A. and the list for so much off-topic materal) If we really wanted to reduce pollution, save money and lives, we would have taken the trillion dollars wasted on the pointless war in Iraq and spent it on geothermal and solar retrofitted systems for every home and business in the U.S. And we would also have the workers that could telecommute instead of wasting gas, time and money driving to and from jobs. This would eliminate the U.S. appetite for so much fuel in the first place. But those in power have a strangle hold on where the money goes and we are forced into thinking we are unable to do anything else. Playing right into the hands of those in power. Off the soap box...
