There was a time when we lived in a place that was green and alive, where trees grew together in clusters we called forests, where we grew food we could eat right from the soil, where we could swim in the creeks after working in the fields and the water felt clean and cold. We could swim in the rivers, too, protected only by our own skin, and in the lakes we could catch fish that we might cook over an open fire after the sun had set. We would gather logs for this from the forest floor, rub two sticks together until they smoked and then with our breath or a bit of wind, they would catch a flame and burn.
