I recall Al Gore's book about the environment. It was so technical, it was unreadable. It was funny when George Bush 41 referred to Gore as "Ozone Man" because of his preoccupation with the ozone layer. I have heard the ozone layer repairs itself. Maybe. The big issue with Gore is global warming. This is the tendency for man-made carbon dioxide to trap heat in Earth's atmosphere. The fear is, the earth will be heated to a point that its polar caps melt, inundating coastal cities. Unchecked, Earth could become a hell like Venus although we would be dead long before. The problem I have is that geologists say we are between Ice Ages. If another Ice Age is inevitable, might not global warming serve as a device for heating the globe? Carbon dioxide in the atmosphere may trap the sun's energy and prevent glaciers from flowing north and south to drive the planet's population toward the equator. It sounds crazy. We are trying to figure out whether we will burn up or freeze to death, whether we are going to drown or die of thirst because all the water is locked up in ice. If global warming is taking place (and apparently it is), I am not sure it is an entirely bad thing. It got pretty cold in Nashville last winter. If it is a bad thing, I am not sure that man in his ingenuity will not find a remedy. I stay mainstream.
