請依下文回答第 25 題至第 28 題      The vast region of unbroken green that surrounds the Amazon River and its tributaries has been under assaultby settlers and developers for 400 years. Time and again, the forest has defied predictions that it was doomed. Butnow the danger is more real and imminent than ever before as loggers level trees, dams flood vast tracts of land,and gold miners poison rivers with mercury. In Peru the forests are being cleared to grow coca for cocaineproduction. “It’s dangerous to say the forest will disappear by a particular year,” says Philip Fearnside of Brazil’sNational Institute for Research in the Amazon, “but unless things change, the forest will disappear.”      That would be more than a South American disaster. It would be an incalculable catastrophe for the entireplanet. Moist tropical forests are distinguished by their canopies of interlocking leaves and branches that sheltercreatures below from sun and wind, and by their incredible variety of animal and plant life. If the forests vanish,so will more than one million species—a significant part of the earth’s biological diversity and genetic heritage.Moreover, the burning of the Amazon could have dramatic effects on global weather patterns—for example,heightening the warming trend that may result from the greenhouse effect.
