Question 2Needs Grading
What role did NC play in the formation of the United States Soil Conservation Service? Who was the first chief of the Soil Concervation Service?
Selected Answer:NC played a huge role in the formation of the US Soil Conservation Service. The first soil conservation district was organized in the Brown Creek watershed of North Carolina. The first chief of the Soil Conservation Service was Hugh Hammond Bennett.
Correct Answer:NC provided the leadership for the US SCS through the first chief, Hugh Hammond Bennett, NC native. NC played a very important role in the policies, research and organization of the SCS through the univerisities and the farming practices used in NC.The following is the biographical information for Hugh Bennett.......Hugh Hammond Bennett was born in a plantation home near Wadesboro, North Carolina in 1881. As a boy, Bennett played, worked, and roamed the acreage of his father's cotton farm. A setting that gave Bennett the opportunity to witness soil erosion while growing up.After earning a degree in chemistry from the University of North Carolina-Chapel Hill, Bennett became a soil surveyor with the USDA's Bureau of Chemistry and Soils. His years of working with the Bureau gave him insight into the effects of erosion on soil and the production of agricultural commodities. He became a nationally recognized authority on the issue through a number of publications and papers he would write.In 1933, as the nation struggled through the Great Depression and Dust Bowl, Bennett was given the opportunity to put his ideas on soil conservation into practice. The Soil Erosion Service (SES) was created within the Department of Interior and Bennett was named its director. Bennett and the other employees of the SES began to holding demonstrations on farms throughout the country.In 1935, the SES was moved to the US Department of Agriculture and renamed the Soil Conservation Service (SCS). Bennett continued as the chief of this new agency.Bennett and his colleagues devised an entirely new approach to land management; putting every acre to its best use and treating every acre according to its needs. Thus was born the conservation plan based on soil resources and their capabilities. This concept involved the ecology of the entire farm -- woods, crops, pastures, and wildlife. Along with the conservation plan, the revolutionary idea of soil conservation districts was born.In 1937, President Franklin D. Roosevelt sent to the governors of all states legislation that would allow the formation of soil conservation districts. The first district established was the Brown Creek Soil Conservation District which included Bennett's home county, Anson.Bennet's flair for showmanship and his evangelistic commitment to soil conservation, convinced national leaders and farmers alike for the need to conserve our soil and water resources. His ideas changed the face of America's landscape. On farmland scared by gullies and blown by winds, lush fields of grain once again waved. Conservation practices like stripcropping, terraces, and waterways had stopped the erosion of our soil and returned the land to its former productivity.In 1951, Bennett retired as chief of the Soil Conservation Service. His influenced had spread worldwide as many other nations emulated the programs he had established in their own country. He was one of the founders of the Soil Conservation Society of America (now the Soil & Water Conservation Society).On July 7, 1960, Hugh Hammond Bennett died of cancer in Burlington, North Carolina at the age of 79. He is buried in Arlington National Cemetery.His legacy lives on in the Natural Resources Conservation Service (formerly the SCS), the nation's 3,000 Soil Conservation Districts, and on the land he worked so hard to protect and enrich.

Question 19Needs Grading
In chapter 12 the issue of urban planning is discussed.1.) Why do we need urban planning?2.) What is urban sprawl? 3. - 5.) List three reasons why the best urban plans may fail when applied to the complex issues of urban sprawl. Use examples from the video you watched for the discussion board or maybe discuss your personal challenges to urban sprawl and planning issues.
Selected Answer:1. We need urban planning because it helps city leaders to come up with long-term objectives that show a vision with the resources needed to acheive it.2. Urban sprawl is the uncontrolled expansion of urban areas.
Correct Answer:Urban planning is a means to monitor growth and provide for the people who are using the space to allow for a full use of resources planning to preserve and provide for the people who live in the urban area - parks, open space, housing. Urban sprawl is the means for people to find these things and more by going out of the city to open land areas and often farther out from the center in search of more house, more space, country.... often exchanging driving for long distances and loss of time for more space.
What are the challenges? 1.) Finding out what people want and developing plans that keep ahead of population growth and 2.) getting these worked into the plan so that people can find what they want in the city, but also it has to be 3.) affordable.
