Desertification (沙漠化) in the dry United States is very serious. Groundwater supplies beneath vast stretches of land are dropping rapidly. Many river systems have dried up. Hundreds of thousands of acres of previously irrigated cropland have been abandoned to wind or weeds. Several million acres of natural grassland are eroded at unnaturally high rates as a result of cultivation or overgrazing (过度放牧). All told, about 225 million acres of land are under severe desertification.
Federal subsidies (补贴) encourage the exploitation of dry land resources. Low-interest loans for irrigation and other water delivery systems encourage farmers and industry to mine groundwater. Federal disaster relief and commodity program encourage dry-land farmers to plow up natural grassland to plant crops such as wheat, especially, cotton. Federal grazing fees that are well below the free market price encourage overgrazing of the commons. The market, too, provides powerful incentives (激励) to exploit dry land resources beyond their carrying capacity.
The incentives to exploit dry land resources are greater than ever. The government is now offering huge new subsidies to produce synthetic fuel from coal oil as well as alcohol fuel from crops. Moreover, commodity prices are on the rise; and they will provide farmers and agricultural businesses with powerful incentives to overexploit arid land resources. The existing federal government cost-share programs designed to help finance the conservation as soil, water, and vegetation are pale in comparison to such incentives.
In the final analysis, when viewed in the national perspective, the effects on agriculture are the most troublesome aspect of desertification in the US. For it comes at a time when we are losing over a million acres of rain-watered crop and grass land per year to higher uses—shopping centers, industrial parks, housing development, and waste dump—regardless of the economic need of the US to export agricultural products or of the world’s need for US food and fiber. Today the dry West accounts for 20 percent of the nation’s total agricultural output. If the US is, as it appears, well in its way toward overdrawing the dry land resources, then the policy choice is simply to pay now for the appropriate remedies or pay for later when productive benefits from arid land resources have been both realized and largely terminated. [br] What can we know about the existing federal government cost-share programs?
选项
A、They cost farmers a lot of money.
B、Their main aim is to develop economy.
C、The government pays less attention to them than to the exploitation of dry land.
D、They are very effective to the exploitation of dry land.
答案
C
解析
细节辨认题。由该旬“联邦政府的现有的成本分摊项目主要是为水土和植被保护提供资金,然而这与前面提到的鼓励措施相比可就逊色多了”可以推知,政府对干涸土地开发的关注度远远大于对水土植被的保护的关注度。故C)为正确答案。
