Consumption can outstrip the natural resources available and lead to overexploitation of the environment. Extravagant consumption can create an environment of raising one’s status among peers. The process of consumption is an economic act, providing the “demand” necessary for the “supply” of the environment. Consumption can generate economic growth that relies significantly on the importation of natural resources, which benefits the environments of less-developed countries. Question 2 Which of the following describes the relationship among population growth, consumption of natural resources, and environmental degradation?

8. When individual demands on natural resources are far greater than the requirements for survival, people in affluent nations deplete resources and degrade the global environment through increased consumption of nonessential items to satisfy their desires. Rapid population growth does not overwhelm and deplete a country’s soils, forests, and other natural resources when the amount of resources essential to an individual’s survival is small. Rate of resource consumption affects the environment far less that the explosion in population. There is no relationship between population growth, consumption of natural resources, and environmental degradation. Question 3 Non-renewable resource is to renewable resource as living is to non-living. limited supply is to sustainable supply. tree is to coal.

Bacteria and fungi are involved in nutrient cycling as they decompose detritus transforming large organic molecules into small inorganic molecules, including carbon dioxide, water, and nutrient minerals like nitrates. Nutrient cycling is the pathway of various nutrient minerals or elements from the environment through organisms and back to the environment. Nonliving processes are also involved in nutrient cycling, such as the weathering of the parent material replaces some nutrient minerals lost through erosion. All of the above statements are true about nutrient cycling.

16. reduce the total amount of pollutants produced. reduce total amounts of pollutants after they are produced. conserve energy. reduce CFC production. Question 2 Why did lead pollution decrease significantly after the creation of the Clean Air Act? Lead is now removed from coal before it is used as fuel. Electrostatic precipitators mandated by the Clean Air Act have greatly decreased the amount of lead being emitted from smokestacks. Catalytic converters in cars greatly reduce the amount of lead emitted. Leaded gasoline was outlawed.
