The Ailing Planet: The Green Movement’s Role……… Mr. Lester R. Brown in his thoughtful book, The Global economic Prospect, points out that the earth’s principal biological systems are four------fisheries, forests, grasslands, and croplands- and they form the foundation of the global economic system. In addition to supplying our food, these four systems provide virtually all the raw materials for industry except minerals and petroleum-derived synthetics. In large areas of the world, human claims on these systems are reaching an unsustainable level, a point where their productivity is being impaired. When this happens, fisheries collapse, forests disappear, grasslands are converted into barren wastelands, and croplands deteriorate. In a protein-conscious and protein-hungry world, over-fishing is common every day. In poor countries local forests and being decimated in order to procure firewood for cooking. In some places, firewood has become so expensive that ‘’what goes under the pot now costs more than what goes inside it’’. Since the tropical forest is, in the words of Dr. Myers, ‘’The powerhouse of evolution”, several species of life face extinction as a result of its destruction. It has been well said that forests precede mankind; deserts follow. The world’s ancient patrimony of tropical forests is now eroding at the rate of forty to fifty million acres a year, and the growing use of dung for burning deprives the soil of an important natural fertilizer. The World Band estimates that a five-fold increase in the rate of forest planting is needed to cope with the expected fuel wood demand in the year 2000.
