cleanly. The chemical products of burned methane are carbon dioxide and water vapor, which arenot pollutants, although they are greenhouse gases.Liquified Natural gas-is extremely hazardous because the mixture of methane and air is explosiveTypes of coal:*In order of increasing heat valueLignite-barely compacted from original peatBituminous-Soft coalAnthracite- Hard coalStrip mining- huge machines strip off the soil and rock above the vein of coal—the overburden to get at the coal beneathThe conventional form of nuclear fission for power production involves the controlled “splitting”of an atomic nucleus of uranium-235, the only naturally occurring fissile isotope. Unlike a fission reaction, which splits an atom, a nuclear fusion reaction forces forms of hydrogen known as deuterium and tritium to combine to form helium, releasing tremendous amounts of energy. The International Thermonuclear Experimental Reactor (ITER)- is intended to be a demonstration plant to prove that fusion can be harnessed as an economically viable source of energy.
Bio-mass fuel-is any organic material produced by plants, animals, or microorganisms that can be burned directly as a heat source or converted into a liquid or gas. Energy Independence and Security Act of 2007- which called for dramatic increases in biofuel production. In the United States, 95% of all ethanol is derived from corn, a fuel with significant disadvantages when com- pared with sugarcane. Salinization- is the concentration of salts in the topsoil as a result of the evaporation of surface water. It occurs in poorly drained soils in dry climates, where evaporation exceeds precipitation. *In the United States, the Clean Water Act of 1972 and subsequent amendments gave wetlands a measure of federal protection. The act prohibits the filling of wetlands without a permit issued bythe U.S. Army Corps of Engineers, a significant change in mission because the Corps of Engineers has long emphasized dredging, stream straightening, and dike building. 1960 Multiple Use Sustained Yield Act—the national forests are to be managed for four purposes: recreation, timber production, watershed protection, and wildlife habitat preservation
Chapter 13/Lecture 13: Human Environment InteractionsEcology-The study of how organisms interact with one another and with their physical environmentBiosphere-the thin film of air, water, and earth within which we live.IPAT equation- is a helpful way of summarizing the different factors influencing the degree of human impact on the environment. The formula is written as Impact on the environment Population, Affluence or standard of living, TechnologyTransboundary water disputes-In many parts of the world, however, water supplies are inad- equate and dwindling. The problem is not with the global amount of water but with its geographic distribution, reliability (the variability of precipitation from year to year), and quality.Tensions are exacerbated in transboundary river basins— areas where two or more countries
