Chapter 14 Key Issue 1 1. A resource is a substance in the environment that is useful to people, is economically and technologically feasible to access, and is socially acceptable to use. 2. The problem is that most resources are limited, and Earth has a tremendous number of consumers. 3. Geographers observe two major misuses of resources: We deplete scarce resources, especially petroleum, natural gas, and coal, for energy production. We destroy resources through pollution of air, water, and soil. 4. Two kinds of natural resources are especially valuable to human’s minerals and energy resources. 5. Historically, people relied primarily on power supplied by themselves or by animals, known as animate power. 6. Energy from flowing water and burning biomass fuel supplemented animate power. Biomass fuel, such as wood, plant material, and animal waste, is burned directly or converted to charcoal, alcohol, or methane gas. 7. Biomass remains the most important source of fuel in some LDCs, but during the Industrial Revolution MDCs converted to inanimate power, generated from machines. 8. Around one-half of the world’s energy is consumed in MDCs and one-half in LDCs. 9. Three of Earths substances provide five-sixths of the world’s energy: Coal, Petroleum, and Natural gas. 10. Coal is supplanted wood as the leading energy source in North America and Europe in the late 1800s. 11. Petroleum was first pumped in 1859, but not an important resource until the diffusion of motor vehicles in the twentieth century. 12. Natural Gas was originally burned off as a waste product of oil drilling, but now used to heat homes. 13. In MDCs other energy comes primarily from nuclear and hydroelectric power. 14. Energy is used in three principal places in the United States: Business, Homes, and Transportation. 15. Businesses are the main energy resource is coal, followed by natural gas and oil.
