We had a new septic system installed a few years ago. When the inspector came out for the perk test we discovered that my lot is all white beach sand about twelve feet down. We were probably waterfront on the one Great Lake before it settled into the five Great Lakes.
What worries me more than CO2 is man-made surfaces that retain heat, i.e. heat islands. But you guys already know that. I'm all for reducing fuel consumption too but not for the CO2 reason. I'm more for it because of the fighting for oil, noise, inefficient city layouts, etc.
