'Environmental Science and Human Populations Worksheet Essay\r'

'Using the textbooks, the University Library, or other resources, answer each of the following questions in 100 to 200 words.\r\n1. What would you include in a brief summary on the history of the forward-looking environmental movement, from the 1960s to the present?\r\nRachel Carson, an author, brought to light the deterioration in using a pesticide c anyed DDT. The pesticide was sprayed to control Dutch elm disease, a fungus that kills trees. The pesticide accidentally killed birds and other wildlife in the process.In 1969 the environmental Policy strike was passed by Congress. in short after that President Nixon recommended the creation of an agency named the Environmental Protection Agency (EPA). In 1970 the Clean line Act was passed, in 1972 the Marine Mammals Protection Act was inducted, and the Endangered Species Act was passed in 1973. In 1974 the dear Drinking Water Act was passed and the Superfund Act was passed in 1980 as a result of a speculative waste problem in New York.\r\n2. formulate the primary concern over exponential nation suppuration. What promotes exponential state growth? What constrains exponential nation growth?\r\nThe primary concerns for the exponential macrocosm growth is how to feed, clothe, house, and support the growing nation with gainful employment. economic growth between and within countries is extremely poor hindering the overall progress.The promotion of exponential population growth can be done with advances in education, health care, and more than freedom and opportunities for women. Exponential population growth is constrained by the abuse and overexploitation of ecosystem resources. This can be improved by provisioning, goods obtained from ecosystems; regulating, run obtained from the regulation of ecosystem processes; and cultural, nonmaterial benefits from ecosystems.\r\n3. What is carrying capacity? Compare predictions for human being population growth in developed countries versus create countrie s. What will occur if carrying capacity is exceeded?\r\nCarrying capacity is the population that can be supported indefinitely by an ecosystem without destroying that ecosystem. According to our textbook, policies and actions that reduce infant mortality profit the availability of family planning. Thus improving air quality, providing rife and pure water, and preserving and protecting natural ecosystems. It will as well as reduce the erosion of the soil, reduces the release of toxic chemicals to the environment, and would revivify health coastal fisheries which all move that gild in a positive direction: a sustain qualified future. Exceeding the carrying capacity is detrimental in many ship canal. The world is already using a substantial amount of fogey fuels thus emitting more carbon dioxide. Society would not be able to sustain natural resources. Food and water supplies would be diminished or tainted. Disease and famine could excessively spread faster without cures or medic ines to control them.\r\n4. How do individual choices affect natural ecosystem? Provide examples from your ain or community experience.\r\nWe as individuals break exponential power to support and help the ecosystem. Cultivating your own diet is a great start. Growing up my family evermore planted a garden. We grew a multitude of vegetables including corn, potatoes, onions, and peppers. What we didn’t use right away we canned or froze so that we would have vegetables year round. I have other family members that raise cows, chickens, and pigs for food. Being able to tender your own food source is self-reliability but it is all organic; no fertilizers or pesticides. Other ways to help the natural ecosystem is by recycling; this would cliff the harvesting of other natural resources. Using start transportation such as bicycles, electronic cars, and hybridisation cars will help diminish the use of fossil fuels that emit carbon dioxide.\r\n'
