CAUSE EFFECT READING ON TOEFL



The Dust Bowl (Question References)
An ecological and economic disaster of unprecedented proportions struck the southern Great Plains in the mid 1930s. The region had suffered several drought years in the early 1930s. Such dry spells occurred regularly in roughly twenty-year cycles. But this time the parched earth became swept up in violent dust storms the likes of which had never been seen before. The dust storms were largely the consequence of years of stripping the landscape of its natural vegetation. During World War I, wheat fetched record-high prices on the world market, and for the next twenty years Great Plains farmers had turned the region into a vast wheat factory.
The wide flatlands of the Great Plains were especially suited to mechanized farming, and gasoline powered tractors, disc plows, and harvester-thresher combines increased productivity enormously. Back in 1830.it had taken some fifty-eight hours of labor to bring an acre of wheat to the granary; in much of the Great Plains a hundred year later it required less than three hours. As wheat prices fell in the 1920s, farmers broke still more land to make up the difference with increased production. Great Plains farmers had created an ecological time bomb that exploded when drought returned in the early 1930s.(A) With native buffalo grass destroyed for the sake of wheat growing, there was nothing left to prevent soil erosion. (B) Dust storms blew away tens of millions of acres of rich topsoil, and thousands of farm families left the region. Those who stayed suffered deep economic and psychological losses from the calamity. (C) The hardest-hit regions were western Kansas, eastern Colorado, western Oklahoma, the Texas Panhandle, and eastern New Mexico. (D) It was the calamity in this southern part of the Great Plains that prompted a Denver journalist to coin the phrase "Dust Bowl."
Black blizzards of du t a mile and a half high rolled across the landscape, darkening the sky and whipping the earth into great drifts of dust that settled over hundreds of miles. Dust storms made it difficult for humans and livestock to breathe and destroyed crops and trees over vast areas. Dust storms turned day into night, terrifying those caught in them. "Dust pneumonia" and other respiratory infections afflicted thousands, and many travelers found themselves stranded in automobiles and trains unable to move. The worst storms occurred in the early spring of 1935.
Several federal agencies intervened directly to relieve the distress. Many thousands of Great Plains farm families were given direct emergency relief by the Resettlement Administration. Other federal assistance included crop and seed loans, moratoriums on loan payments, and temporary jobs with the Works Progress Administration. In most Great Plains counties, from one-fifth to one third of the families applied for relief; in the hardest-hit communities as many as 90 percent of the families received direct government aid. The Agricultural Adjustment Administration paid wheat farmers millions of dollars not to grow what they could not sell and encouraged the diversion of acreage from soil-depleting crops like wheat to soil-enriching crops such as sorghum.
To reduce the pressure from grazing cattle on the remaining grasslands, the Drought Relief Service of the Department of Agriculture purchased more than 8 million head of cattle in 1934 and 1935. For a brief time, the federal government was the largest cattle owner in the world. This agency also lent ranchers money to feed their remaining cattle. The Taylor Grazing Act of 1934 brought stock grazing on 8 million acres of public domain lands under federal management.
The federal government also pursued longer-range policies designed to alter land-use patterns, reverse  oil erosion, and nourish the return of grasslands. The Department of Agriculture, under Secretary Henry A. Wallace, sought to change farming practices. The spearhead for this effort was the Soil Conservation Service (SCS), which conducted research into controlling wind and water erosion, set up demonstration projects, and offered technical assistance, supplies, and equipment to farmers engaged in conservation work on farms and ranches. The SCS pumped additional federal funds into the Great Plains and created a new rural organization, the soil conservation district, which administered conservation regulations locally.
By 1940 the acreage subject to blowing in the Dust Bowl area of the southern Plains had been reduced from roughly 50 million acres to Jess than 4 million acres. In the face of the Dust Bowl disaster, New Deal farm policies had restricted market forces in agriculture. But the return of regular rainfall and the outbreak of World War II led many farmers to abandon the techniques that the SCS had taught them to accept. Wheat farming expanded and farms grew as farmers once again pursued commercial agriculture with little concern for its long-term effects on the land.
