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 renewedthrough normal processes of reproduction. Nor is simply diminishing numbers.Nor is it damage that can somehow be remedied or for which some substitute canbe found. Nor is it something that only affects our own generation. Nor is it somethingthat could be remedied by some supernatural power. It is, rather, an absoluteand final act which there is no remedy on earth or in heaven. A species onceextinct, it's gone forever. However many generations succeed us in comingcenturies, none of them will ever see this species that we extinguish. Not onlyus we bring about extinction of life on a vast scale. We are also making theland 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 beingused up in a of frenzy of processing, consuming and disposing but we are alsoruining much of our renewable resources. Such as the very solid self on which terrestriallife depends. The change that is taking place on the earth and in our minds isone of the greatest changes ever to take place in human affairs. Perhaps thegreatest, since we are talking about is not simply another historical change orcultural modification. But it change the geological and biological as well as psychologicalorder of magnitude.
