            For many environmentalists, the world seems to be getting worse. They have developed a hitlist of our main fears: natural resources are 1 out? the population is ever growing, leaving less and less to eat? species are becoming 2 in vast numbers, and the planet'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 3 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 4 of the world's population than at any time in history. Fewer people are 5 . Third, although species are indeed becoming extinct, only about 0.7% of them are expected to disappear in the next 50 years, not 25~50%, as has so often been 6 . And finally, most forms of environmental pollution either appear to have been 7 , or are transient - associated with the early stages of industrialization and therefore best cured not by restricting economic growth, but by 8 it. One form of pollution - the release of greenhouse gases that causes global warming - does appear to be a phenomenon that is going to extend well into our future, but its total impact is unlikely to 9 a devastating (令人心神不安的) problem. A bigger problem may well turn out to be an inappropriate response to it.
