...vast region of unbroken green that surrounds the Amazon River and its tributaries has been under assault by settlers and developers for 400 years. Time and again, the forest has defied predictions that it was doomed. But now 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 cocaine production. "It's dangerous to say the forest will disappear by a particular year," says Philip Fearnside of Brazil's National Institute...
Scientists are concerned that the destruction of the Amazon could lead to climatic chaos. Because of the huge volume of clouds it generates, the Amazon system plays a major role in the way the sun's heat is distributed around the globe. Any disturbance of this process could produce far-reaching, unpredictable effects. Moreover, the Amazon region stores at least 75 billion tons of carbon in its trees, which when burned spew carbon dioxide into the atmosphere. Since the air is already dangerously overburdened by carbon dioxide from the cars and factories of industrial nations, the torching of the Amazon...
...interlocking leaves and branches that shelter creatures below from sun and wind, and by their incredible variety of animal and plant life. If the forests vanish, so will more than 1 million species -- a significant part of 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. "The Amazon is a library for life sciences, the world's greatest pharmaceutical laboratory and a flywheel of climate," says Thomas Lovejoy of the Smithsonian Institution...
...passions behind the fight are easy to understand for anyone who has seen the almost unimaginable sweep of the Amazon basin. The river and forest system covers 2.7 million sq. mi. (almost 90% of the area of the contiguous U.S.) and stretches into eight countries besides Brazil, including Venezuela to the north, Peru to the west and Bolivia to the south. An adventurous monkey could climb into the jungle canopy in the foothills of the Andes and swing through 2,000 miles of continuous 200-ft.-high forest before reaching the Atlantic coast. The river itself, fed by more than...
...diversity of the Amazon is more than just good material for TV specials. The rain forest is a virtually untapped storehouse of evolutionary achievement that will prove increasingly valuable to mankind as it yields its secrets. Agronomists see the forest as a cornucopia of undiscovered food sources, and chemists scour the flora and fauna for compounds with seemingly magical properties. For instance, the piquia tree produces a compound that appears to be toxic to leaf-cutter ants, which cause millions of dollars of damage each year to South American agriculture. Such chemicals promise attractive alternatives to dangerous synthetic pesticides. Other...
