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
