Imperilled Riches CONSUMPTION Excessive consumption in wealthier countries contributes to rainforest destruction in tropical countries. For example, during the 1970s and 1980s American demand for cheap beef triggered the clearing of vast stretches of rainforest in Central America and Brazil. Similarly our demand for certain forest products like tropical hardwoods and cheep particle board gives impetus for companies to exploit forest stocks. Japan converts thousands of acres of tropical rainforest every year into wood framing for cement blocks (discarded after the cement dries) and chopsticks. The cultivation of cassava in Thailand for European cattle feed increased more than ten-fold from 1965 to the mid-1980s causing extensive deforestation in northeastern Thailand. The top 20% wealthiest countries consume 86% of world resources, while the bottom 20% consumes only 1.3%. Excessive energy use and waste in the developed countries means that each person in the north has a much greater impact on the earth's environment than each person in developing countries. Each child in the Britain produces as much carbon dioxide and pollution as 30 born in Bangladesh in a given year. Therefore, the 58 million people added to the Earth in developed countries during the 1990s will pollute more than the 915 million people added in developing countries during the same period. In other words, with current consumption patterns, overpopulation in the United States (population growth rate roughly 1%) is more of a threat to the Earth's environment than overpopulation in Angola (population growth rate of 3.7%). CONCLUSION The world's tropical rainforests are threatened by short-term economic exploitation of their resources and pressures from the rural poor. These short-term demands incur long-term costs, which are still largely unrealized and unknown. Because it is easier and appears more economical to clear the forest in the short run, our future quality of life is compromised. The consequences of our actions is the focus of the next chapter. |
