Nevertheless, I believe that the distant future of the balance or unbalance between humankind and nature has a great importance. Certainly, if we look far enough ahead, it will be beyond our own lifetimes. But I feel that we we should think not only of our own children, and of their children and grandchildren, but also about the fate of all future human generations; and not only about humans, but also about what will happen to all the animals and plants and microbes with which we share our existence.
