Gaviotas, a rural area in Colombia, is an example of how even desolate places in the countryside can be developed for sustainable human use. This area had been considered a wasteland: dry brown savanna, without enough water, plant, or animal life to support a town. But today a green spot of a 25,000-acre forest and big aluminum sunflowers begin to dot the empty savanna.
Under the trees are low white buildings and colorful houses, all with solar collectors. Begun in 1971 as a scientific experiment, Gaviotas is now a self-sufficient town of 200, supported by clean, renewable industries. In the beginning of restoring the unproductive savanna to a place where humans can live well, the first problem was finding pure water. The Gaviotans invented a special kind of hand pump to reach deepwater reservoirs. Another goal was to restore the soil and plants. After years, they discovered that Caribbean pines from Honduras could grow in the area’s thin, acidic soil.
As more people moved to Gaviotas, it was important to consider a pollution-free way of transportation. Village mechanics developed a bicycle especially designed for the area’s rough land. Bicycles are now the official mode of transportation, cheap and pollution-free. Gaviotas is a remarkable accomplishment of sustainable development. This once dry landscape has been turned into a near paradise. 【題組】20 Which of the following statements is NOT true?
