Mankind has discovered that he may harvest energy, as well as fruits, vegetables, nuts, and berries, from Nature. He presumes that he is entitled to exploit these resources with no thought of paying Nature, putting anything back, or cleaning up. Now, he is in a bind. His life is filled with feverish activity. He knows that he has way too great an impact on the environment. But he can't stop. He has credit card debt. He just barely avoided the last big lay-off at his job. His wife has been bugging him to earn more money, in keeping with the normal measure of worth in his society, usually referred to as status. He has a brokerage account; but, he has been unable to earn extra money by trading stocks, options, and other securities. This man's troubles will be recognized as instances of the modes in which Capitalist economies achieve the economic growth they require.
But, all of this activity, from which Capitalism will not let up but demands more of the same is in violation of the Fundamental Principle of Ecology (now promoted to initial caps). Thus, Capitalism's route to inevitable collapse is the greatest evil in the world today.
