DDT and Modern Environmentalism – II

Lead: In 1962 Rachel Carson animated the national conversation with Silent Spring, an explosive book describing the environmental havoc caused by .DDT.

Intro.: A Moment in Time with Dan Roberts.

Content: At first DDT, dichloro-diphenyl-trichloroethane, seemed a miracle. Modern agricultural practices had produced greater crop yields but had opened the way to greater infestation by pest insects. Some chemical insecticides were tried, but not until arrived in the late 1930s did there appear to be a true solution to the problem of insect control. As soon as the chemical gained USDA approval for use on plants and agricultural commodities, farmers snatched it up and crop production soared. The grayish white powdered insecticide killed nearly every insect which consumed it by interrupting respiration at the cell level. The insects literally suffocated from the inside out.

DDT and Modern Environmentalism – I

Lead: It seemed to be a miracle. Farmers worldwide looked ahead to the prospect of lush fields of produce free of pests. All they had to do was use DDT.

Intro.: A Moment in Time with Dan Roberts.

Content: In the years following the Civil War, the United States Government, through the newly created Department of Agriculture, began to aggressively promote industrialized agriculture. It was an amazing success. Techniques developed at land grant colleges and applied by county extension agents brought a new level of technology to the ancient practice of growing food. Increased efficiency and mechanization made the American farmer the envy of the world. Per capita output soared and farm population began to shrink thus providing workers for growing urban industrial enterprises.

Guano

Lead: As world population grew in the years before and after 1800 so did the demand for food. At the same time, much farm acreage was depleted, tired, unproductive. This problem was solved in part with guano.

Intro.: A Moment in Time with Dan Roberts.

Content: Guano is bird excrement. Grouped with the droppings of bats and seals, it is perhaps the most potent natural fertilizer, and bird guano is the primo variety containing up to 16% nitrogen, 12% phosphorus, and 3% potassium.

I offer you in their place: work—hard, hard work, the task of bringing a people from degradation, poverty, and waste…. Your department exits only on paper and your laboratory will have to be in your head.” Carver spent the rest of his life at Tuskegee.

Samuel Johnson and the Agricultural Revolution

Lead: During Samuel Johnson’s lifetime, improvements in farming resulted in a greater food supply. Johnson who loved eating said, “Some people have a foolish way of not minding, or pretending not to mind, what they eat. For my part, I mind my belly very studiously, and very carefully; for I look upon it, that he who does not mind his belly, will hardly mind anything else.”

Intro.: A Moment in Time with Dan Roberts.

Content: Although most historians focus on the Industrial Revolution in England during the 18th century, there were also sweeping changes out in the countryside. Britain was being transformed from an agrarian society to an industrial one, but somebody had to feed the growing number of workers occupying the urban factories. One of the great factors fueling the industrial revolution was great increase in agricultural production, which meant that fewer farmers could produce more food. This in turn, supported an enormous surge in population.
