One result of the Green Revolution of the 1970s was: a reduction in the amount of chemical fertilizers used for crop growth. new inbred seeds becoming more resistant to diseases than traditional seeds. a reduced need for irrigation, dramatically saving fresh water resources. improved soil quality from new technology that also polluted water sources. According to your textbook, what factor is most likely to contribute to a global food shortage? deforestation. sea levels decreasing. rural migration. arable land decreasing. QUESTION 3 1. At the present rate of economic growth in the developed world, what can we expect for the future? A decrease in the availability of freshwater will make irrigation more limited. Major grain-producing areas will find new sources of freshwater for irrigation. Less fossil fuels will be used because of the increase of nuclear energy. New sources of food and energy production will make climate change less of an issue. QUESTION 4 1. One reason people do not get enough to eat in a country is because: Its infrastructure system is in excellent condition. There is little or no civil strife among its people. Some crops are often grown for export, leaving little to consume internally. The government does not discriminate in food allocation based on tribe or ethnicity. QUESTION 5 1. With respect to farming trends in the developing world, which of the following is true? The inadequate drainage of water may lead to the loss of arable land. Irrigations systems are leading to an increase of arable land. Soil is becoming more toxic, harming farmland. Crop rotation to replenish nutrients is becoming less necessary. QUESTION 6 1. We can expect all of these in the future, except: a sustained increase in the prices of commodities. a growth in global greenhouse gas emissions. a decrease in the use of coal as an energy source. a long-term decline of soil quality. QUESTION 7 1. Which is most likely to occur if we continue with current practices in farming and resource usage? There will be an increase in people moving from urban to rural areas. There will be an increase in the prices of commodities. There will be a decrease in the use of fossil fuels by developed countries. There will be a decrease in the number of people living in developing countries. QUESTION 8 1.

Current United Nations models of global population growth and food production lead to the prediction that: the problem of limited natural resources will be resolved to the point where these resources will be produced in abundance. the upward trend of global warming will be reduced by eliminating greenhouse gases. a cooling trend of the oceans will make their ecosystems productive for the world’s fishing industries again. an increase in the general GDP of the world’s states will place additional pressure on the demand for natural resources. QUESTION 10 1. Which part of the world has seen the most significant decrease in the number of people living in extreme poverty since 1981? Refer to the charts in Figure 2.2 (pg 54 of your textbook). Sub-Saharan Africa South Asia East Asia and Pacific Middle East and North Africa Part 2 QUESTION 1 1. Which of the following factors contributes most to soil erosion? rural migration deforestation urban migration climate cooling QUESTION 2 1. Current models of climate change indicate that: the majority of people are moving away from urban areas and into rural areas. the majority of the world’s population will live in cities by the year 2050. scientific advancements are leading to a decrease in greenhouse gas emissions. an increase in world economic growth will lead to a decrease of fossil fuels.

If we need to grow 50 percent more food to supply the Earth’s population increase by 2030, what is the most likely result? New sources of freshwater will be discovered. The current supply of freshwater will be increased. The increased use of chemical fertilizers will continue to contaminate freshwater. There will be increased demand for freshwater for irrigation purposes. a and b. c and d QUESTION 8 1. Using Figure 2.2, what area has seen the most significant increase in the number of people living in extreme poverty since 1981?
