Only after aggressive government intervention did the Dust Bowl conditions improve. The government, even before the drought was broken in 1939, was able to reduce soil erosion by 65% through the actions of the Civilian Conservation Corps, which planted 200 million trees to "break the wind, hold water in the soil, and hold the soil itself in place" ("Disasters: The 1930s," U.S. History, 2011). Farmers received instruction by the government on "soil conservation and anti-erosion techniques, including crop rotation, strip farming, contour plowing, terracing and other beneficial farming practices" ("Disasters: The 1930s," U.S. History, 2011). For the first time, the government took an interest not simply in preserving some of its land from development in the form of national parks, but gave counsel to farmers how to use the land.
The gap between the 'haves' and the 'have-nots,' already wide even before the Great Depression, grew into a chasm in the years after the Great Crash. While few people were unaffected by the Depression, the poor suffered the most "Unemployment rose from a shocking 5 million in 1930 to an almost unbelievable 13 million by the end of 1932" ("Life during the Great Depression," All about History, 2011). Increasingly, there were calls for the Hoover Administration to treat the Depression's causes and provide some relief. The Hoover Administration's most vocal critic was that of John Maynard Keynes, a British economist who had advocated a radical reworking of conventional economic theory.
According to classical economic theory, as prices fall during a recession, or a natural trough in the business cycle, eventually demand will increase as prices decrease to such a level there is a tremendous incentive to buy goods and services. Producers expand production to meet the new surge in demand, hire more workers, and the business cycle once again surges upward into an expansionary period. Keynes, however, noted that when people are frightened of losing their jobs, they are not interested in spending more money, and instead save money. They hide money under the mattress -- literally, in the case of the Great Depression, given the catastrophic bank runs that depleted confidence in the national banking system immediately after the crash. "At the start of the Depression, the federal government did not guarantee bank deposits, so...

However, contributor, William Farr, provided substantial information data understanding etiology spread cholera research surveillance John Snow is known as the founder of modern epidemiology. Summarize his works and findings, describing the premise on which his experiments were formulated. How did Snow explain that cholera's first symptoms were abdominal pains? How does his work demonstrate the scientific method? Snow first
Snow, in contrast to Farr's epidemiology, was far more innovative and spontaneous in his methods, which also made his conclusions, in the eyes of his colleagues more suspect. As well as doing his own hands-on research, Snow analyzed the "natural experiment created when one water- supply company of London, the Lambeth Company -- but not the Southwark and Vauxhall Company -- moved its water inlet to a less polluted area
