Find out whether the following statements are true or false or not given . 1. Envrionmetalists take a pessimistic view of the world for a number of reasons. For many envrionmentalists, the world seems to be getting worse. They have developed a hit-list of our mian fears: that natural resources are running out; that the population is ever growing, leaving less and less to eat; that the species are becoming extinct in vast numbers, and that the people's air and water are becoming ever more polluted. But a quick look at the facts shows a different picture. First, energy and other natural resources have become more abundant, not less so, since the book "The Limits to Growth" was published in 1972 by a group of scientists. Second, more food is now produced per head of the world's population than at any time in history. Fewer people are starving. Third, although species are indeed becoming extinct, only about 0.7% of them are expected to disappear in the next 50 years, not 20-25%, as have been exaggerated, or are transient-associated with the early phases of industralizartion and therefore best cured not by restricting economic growth, but by acclerating it. One form of pollution-the release of greenhouse gases that cause global warming-does appear to a phenomenon that is going to extend well into the future, but its total impact is unlikely to pose a devestating problem. A bigger problem may well turn out to be an inappropriate response to it.
