Whether the world is 6000 years old, or 2 million years old, its ALL we have. And when and if it ends for us, who, or what is going to care. Whether I came from the sea, or out of a tree, who's going to care when I'm or we are gone? Think fossil fuels don't or didn't cause major change? Panama canal, grand coulee dam, aswan dam suez canal. Wont go into super highways, airplanes steam ships. All these wonders are man made.They solved many problems. But remember cause and effect? But there are things that have followed man from the beginning. War, hunger, pestilence, and over population. Those are cold hard cures. Those are constants we can't do anything about. I'm just an old guy,with nothing to do, except look at the follys of the world.
