Chapter 8 Environment Links to Health Introduction The Petrochemical Industry: Links to Health  The petrochemical industry manufactures products largely using raw materials, such as crude oil (petroleum) and gas.  Rachel Carson argued that carcinogens are produced from these industries in such great amounts that their effects are health throughout our environment. The Industry’s Effect on the Air We Breathe  The source of smog is from ground level ozone, which is formed through a chemical reaction of pollutants from industrial plants and vehicle emissions combined with sunlight and stagnant air.  There are four known health effects from smog: respiratory disease, cardiovascular disease, allergies and neurological effects.  In the late 1970s, the depletion of the earth’s ozone layer was linked to a chemical called chlorofluorocarbon (CFC)  There has been a dramatic drop in the use of ozone depleting substances, however, scientist continue to be concerned for three primary reasons; 1) there is uncertainty whether the ozone layer can be return to its original thickness; 2) in recent years. The production and use of CFCs has recently increased; 3) there is a decreasing sense of urgency to this problem as there is a popular misperception that ozone depletion has resolved itself. The Industry’s Effect on the Land that Feeds Us  The effect of the petrochemical industry is specifically note worthy with regard to the manufacturing of pesticide for use in modern agriculture.  In 1939, a Swiss chemist by the name of Paul Muller developed a compound called dichlorodiphenyltrichloroethane more commonly known as DDT.  Many advantages to pesticide use were offered, including the following: pesticides greatly increase crop production without rotating crops; they are highly cost effective and one farmer is able to work a large piece of land efficiently; there is decreased soil loss; and produce is picture perfect, which consumers have grown to demand.  DDT belongs to a group of chemicals in the environmental movement commonly referred to as persistent organic pollutants, betters known as POP.  POPs have been linked to cancer, to nervous system and reproductive disorders, and to birth defects.  As well, they are known to be endocrine disruptors – they mimic natural hormones circulating in the body, either enhancing or blocking the production of these hormones.  POPs have been found throughout the world, often thousands of miles from the source of it use. The Industry’s Effect on Farming  Pesticide use since WWII had changed the face of farming.  Farming had become more intensive, with each acre of land producing higher yields  Even though the number of arms has steadily declined since 1961, crop production has increased where ‘the real value of production has tripled.’ PEI Potato Farming: A Case Study  Linda Van Til, an epidemiologist for the PEI Department of Health, believed that cancer trends in Pei are no different than those in the rest of Canada.  However, Dr Matsusaki, who worked in numerous emergency rooms across Canada and the United States disagrees that cancer is not a problem in PEI.  According to Steingraber, farmers experience such cancers as prostate, melanoma, and multiple myeloma at much higher rates than the rest of the population.  Carson, in the early 1960s, identified three forms of silence that ultimately serve industry, not people.  Two forms of silence continue to be relevant today: 1) environmental debates occur and stay behind closed doors of government offices; and 2) ‘the hushed complicity of many individuals scientists who were aware of – if not directly involved in documenting – the hazards created by chemical assaults on the natural world.’ How Agribusiness Control Food, the Environment, and Our Health  Farming today is part of an integrated larger system t
