16. Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings Science and Society Most scientist agree that the most pressing environmental issue facing human society is population growth. Scientist disagree on whether the rising rate of consumption in the developed countries is a greater problem than the rapid population growth in undeveloped countries. How do you rate this problem? Developed countries’ consumption A. E. C. B. D. Under developed countries’ population growth

17. Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings Science and Society Renewable resource management is challenging. Populations of whitetail deer today live in areas with few natural predators. Their populations have expanded exponentially. Population control methods include hunting—even in urban areas. Do you think that controlled hunting should be used to manage deer populations in urban areas? Strongly Agree A. E. C. B. D. Strongly Disagree

18. Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings Science and Society Populous nations such China have instituted strict policies to curb population growth. In 1979, China implemented a “one-child” policy. Do you think that such strict control methods are appropriate for population control? Strongly Agree A. E. C. B. D. Strongly Disagree
