Unit 24

Ecology

Before you read

Discuss the question:

How and why has ecological damage become a major global issue?

Now read the text. What does it say about the question above?

The Aral Sea, located high in the steppes of central Asia, was once the world’s fourth largest freshwater lake and a thriving ecosystem. In the 1960s, central planers in the former Soviet Union decided to divert water from the two major rivers feeding the Aral Sea to irrigate the surrounding plains. Agriculture flourished, but results for the lake were disastrous. By the 1980s, the Aral Sea, cut off from its water sources, had lost 60 percent of its volume and was three times as salty as normal. The fishing industry, which supported 60.000 jobs in the 1950s, shut down because all the fish disappeared. In the early 1990s, the five newly formed republics in the Aral basin were faced with deciding what to do. Any meaningful effort to restore the ecological health of the Aral Sea would certainly require international aid.

Astronauts orbiting the earth in the Discovery spacecraft in 1993 were startled to observe huge plumes of black smoke rising from the South American continent, drifting high into the atmosphere. The smoke they saw was coming from tropical rain forests, being deliberately burned to clear land for cattle ranching, farming, and housing. During the 1980s, Brazil lost on average about 5 million acres of rain forest a year. This development came at great cost. Many species were destroyed, and widespread burning injected carbon into the atmosphere, contributing to global warming. Some economists believed that the long-term value of the rain forest would be much greater if it were cleared.

In the early 1990s, hundreds of thousands of tons of waste, much of it hazardous, were exported from the United States. Some was loaded on ships bound for the Far East. One destination was the Guo Fu smelter, a scrap-metal processing facility near Zhuhai City in southern China. Here, workers earned $2 a day dismantling old car batteries, electrical motors, transformers, and even used computers. The Chinese government welcomed the project, a joint venture with a U.S. firm, because it provided jobs and earned valuable foreign exchange when recycled copper, aluminum, and steel were shipped out of the country. But in a ravine behind the facility, unusable materials – including polychlorinated biphenyls, and other heavy metals – were carelessly dumped, threatening the long-term health of residents in the area.
