At current consumption rates, a child born today in an industrialized country will add more to consumption and pollution during her/his lifetime than 1)5-10 children born in developing countries. 2)10-15 children born in developing countries. 3)20 children born in developing countries. 4)30-50 children born in developing countries.

Copyright © 2009 Pearson Education, Inc. Thinking Like a Scientist This figure plots the breeding populations of fur seals as they recovered from uncontrolled hunting. Based on this graph what is the approximate carrying capacity of the fur seal’s breeding habitat? 1)About 1000 seals. 2)About 5000 seals 3)About 10,000 seals

Copyright © 2009 Pearson Education, Inc. Science and Society Most scientists 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? Disagree Agree Strongly A B C D E Strongly

Copyright © 2009 Pearson Education, Inc. 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? Disagree Agree Strongly A B C D E Strongly

Copyright © 2009 Pearson Education, Inc. Science and Society Populous nations such as 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? Disagree Agree Strongly A B C D E Strongly
