Environmental topics pervade classrooms today, but true understanding of them is elusive. All too often, subjects such as global warming, species extinction, and the role of pesticides are reduced to simple slogans because accurate information is hard to find. Yet there is enormous scientific debate about these topics. Thomas Jefferson said that "difference of opinion leads to inquiry, and inquiry to truth." Critical Thinking About Environmental Issues will prepare young people to become inquiring citizens by introducing them to the scientific and economic debates that underlie environmental issues. Each volume will provide readers with a range of scientific views and theories on an environmental topic and introduce facts that are sometimes ignored. Each will help readers use their critical thinking skills. By exposing students to differences in opinion, this series will enable them to search for the truth and to make their own decisions.
