Editor Clare Hanrahan has compiled several essays that debate four key issues relating to our global resources. Are global resources overstrained? What global agricultural policies should be pursued? What alternative energy sources are worth pursuing? How can the world's resources be preserved? Across four chapters readers will evaluate the divergent viewpoints that debate the answers to these questions. Readers can use critical thinking skills to form their own intelligent opinions. Essay sources include the African American Environmentalist Association, National Renewable Energy Laboratory, Food and Agriculture Organization of the United Nations.
