　　Extinction is a difficult concept to grasp. It is an eternal concept. It is not at all like the killing of individual life forms that can be renewed through normal processes of reproduction. Nor is simply diminishing numbers. Nor is it damage that can somehow be remedied or for which some substitute can be found. Nor is it something that only affects our own generation. Nor is it something that could be remedied by some supernatural power. It is, rather, an absolute and final act which there is no remedy on earth or in heaven. A species once extinct, it’s gone forever. However many generations succeed us in coming centuries, none of them will ever see this species that we extinguish. Not only us we bring about extinction of life on a vast scale. We are also making the land and the air and sea so toxic that the very conditions of life are being destroyed. As regard natural resources ,not only are the none renewable resources being used up in a of frenzy of processing, consuming and disposing but we are also ruining much of our renewable resources. Such as the very solid self on which terrestrial life depends. The change that is taking place on the earth and in our minds is one of the greatest changes ever to take place in human affairs. Perhaps the greatest, since we are talking about is not simply another historical change or cultural modification. But it change the geological and biological as well as psychological order of magnitude.
