They have been a fact of life(1) for thousands of years. However, few people lived in desert regions in the past. They kept few animals, and they moved frequently. Today's problems are caused in great part by distinctly modern factors. In the Sahel, example. for example. Africans benefited from improvements in public health and modern farming methods. New water wells encouraged people to settle down on the land near the wells. The population grew. Farmers planted more crops and enlarged their herds of cattle, sheep, and goats. They became dependent on the new wells. When the drought came, the crops failed and the cattle ate all the grass around the overworked wells. The fragile land quickly lost its topsoil and became nothing but sand and dust. Many countries are experiencing similar problems. Poor land is farmed until it is worn out, and trees are cut for firewood, leaving the soil unprotected against wind and rain. In Peru, Chile, and Brazil, some areas that once were covered with forests now look like the moon. In India, some land has been so badly damaged by farming and tree cutting that mud now slides into the Indus and Ganges rivers. Cattle, sheep, and goats add to the problem by eating grass and other plants faster than they can grow back. In the United States, some highly deserts. Water must be piped in from hundreds of miles away and this affects the water supply of other California communities. Scientists still do not understand all the complex problems of the desert, but there have been many ideas for saving the land. Saudi Arabia has planted 10million trees to help keep the sand from taking over(2) fertile areas. The Israelis are again using some of the water collection systems left by the ancient peoples in the Negev desert. They plan to water their orchards with the extra water. Some Sahel farmers still raise cattle on their poor farm land, but before the cattle are sold, they are taken to greener lands in the south to get fat. The spread of the desert affects most countries. The big question today is, how can an expanding world population find food and space without destroying the land it lives on? For many countries, battling the desert is the only chance to avoid starvation, destruction, and disaster. 답변자 ts0075 답변일 2014-12-03 답변내용 Droughts and crop failures are not new in desert regions. ☁ Droughts and crop failures are not new in desert regions.
