113. What is point source pollution? Two main sources include:

1) Point source pollution is a pollution that enters a body of water from a specific source.2) a. Water-using manufacturers. Many factories and power plants use water for cooling and then discharge the warm water back into the river or lake. The warm water may not be polluted with chemicals, but it raises the temperature of the body of water it enters. Fish adapted to cold water might not be able to survive in the warmer water. Steel, chemicals, paper products, and food processing are major industrial polluters of water. Each requires a large amount of water in the manufacturing process and generates a lot of waste water.b. Municipal sewage. In developed countries, sewers carry waste water from the sink, bathtub, and toilets to a municipal treatment plant, where most of the pollutants are removed. The treated wastewater is then typically dumped back into a river or lake. In developing countries, sewer systems are rare, and wastewater often drains, untreated, into rivers and lakes. The drinking water, usually removed from the same rivers may be inadequately treated as well. The combination of untreated water and poor sanitation makes drinking water deadly in some developing countries.

69. The largest flows of oil are from ____________, and from ____________ and to _____.

1) Russia to Europe2) Southwest Asia to Europe3) Japan

What happens if there is too much waste discharged into a water source? What happens if there is a run off of fertilizer into a water source?

1) The water becomes oxygen starved and the fish die.2) This condition is typical when water becomes loaded with municipal sewage or industrial waste. The fertilizer nourishes excessive aquatic plant production, a pond scum of algae that consumes too much oxygen. Either type of pollution reduces the normal oxygen level, threatening aquatic plants and animals. Some of the residuals may become concentrated in the fish, making them unsafe for human consumption.

83. Why is generating electricity from nuclear power plants more expensive than from coal-burning plants?

Nuclear power plants cost several billion dollars to build, primarily because of the elaborate safety measures required. Without double and triple backup systems at nuclear power plants, nuclear energy would be too dangerous to use. Uranium is mined in one place, refined in another, and used in still another. As with coal, mining uranium can pollute land and water and damage miners' health. The complexities of safe transportation add to the cost.

62. Why was OPEC (the Organization of the Petroleum Exporting Countries) formed in 1960?

OPEC was originally formed to enable oil-rich countries to gain more control over their resource. U.S. and European transnational companies, which had originally explored and exploited the oil fields, were selling the petroleum at low prices to consumers in developed countries and keeping most of the profits. Countries processing the oil reserves nationalized or more tightly controlled the fields, and prices were set by governments rather than by petroleum companies.
