Examples include pollution, resource depletion, loss of biodiversity, and overpopulation.PTS:1DIF:3REF:1OBJ:53.ANS:Answers may vary but may include: life expectancy, population growth rate, and energy use.PTS:1DIF:3REF:2OBJ:44.ANS:biodegradable, breaks down; nonbiodegradable, does not break down by natural processesPTS:1DIF:3REF:1OBJ:55.ANS:Answers may vary but may include: renewable—sunlight, water, and air; nonrenewable—fossil fuels, minerals, and metals.PTS:1DIF:3REF:1OBJ:46.ANS:biology, chemistry, physics, social sciences and earth sciencePTS:1DIF:3REF:1OBJ:27.ANS:Answers may vary but may include: more efficient agriculture, industry, and transportation; less expensive production of goods; improved sanitation, nutrition, and medical care.PTS:1DIF:3REF:1OBJ:38.ANS:burned prairie to maintain grasslands, over-hunted large mammalsPTS:1DIF:3REF:1OBJ:39.ANS:Industrial Revolution; list of problems may vary but may include: pollution from fossil fuels, large-scale loss of natural habitats, beginning of consumption crisis, and rapid population growth.PTS:1DIF:3REF:1OBJ:3PROBLEM1.ANS:Brazil lost approximately 27,000 square kilometers in 1990 and about 10,000 square kilometers in 1980. This is a difference of 17,000 square kilometers of tropical rain forest lost.PTS:1DIF:3REF:1OBJ:52.ANS:India lost approximately 9,000 square kilometers in 1990. 9,000???50?percent?=?4,500 square kilometers. Therefore, India’s loss in 2010 would be 9,000?+?4,500 square kilometers, equaling 13,500 square kilometers. Alternate solution: 9,000???150 percent?=?13,500 square kilometers.PTS:1DIF:3REF:1OBJ:53.ANS:Approximate combined loss (in square kilometers for 1990): 4,000 (Myanmar)?+?2,500 (Thailand)?+?5,000?(Indonesia)?=?11,500 square kilometers lost. Approximate combined loss (in square kilometers for 1980): 1,000?(Myanmar)?+?3,000?(Thailand)?+?3,000?(Indonesia)?=?7,000 square kilometers lost. The formula to find the percentage change is: “the amount of change” divided by “the original amount.” The amount of change is 4,500 square kilometers. (11,500?–?7,000?=?4,500). The original amount is 7,000 square kilometers. 4,500???7,000?=?0.6428, which rounds off to 64 percent. Therefore, the loss of rain forest increased by 64 percent in 1990 as opposed to 1980 figures.PTS:1DIF:3REF:1OBJ:5ESSAY1.ANS:Answers may vary but should mention the high rates of consumption in developed countries and the amount of land and sea required to support residents of such countries.PTS:1DIF:3REF:2OBJ:32.ANS:Answers may vary but may include: introduction of pollution controls during the Industrial Revolution, developing effective agricultural practices that could be shared worldwide, preserving natural areas to reduce species loss and protect habitats, developing cleaner fuels, and de-emphasizing consumption.PTS:1DIF:3REF:1OBJ:5 ................
