Climate change is one of the most serious problems of the twenty-first century. Should issues related to climate change be considered the responsibility of environmentalists, ecologists, or both? Oa) Environmentalists, because they consider ecological knowledge along with public policy. Ob) Both ecologists and environmentalists, because neither is equipped to control climate change on their own. c) Both ecologists and environmentalists, because a scientific understanding of climate change is needed to make reasonable policy decisions. Od) Ecologists, because scientists are best able to quantify the changes taking place. e) Environmentalists, because the most important effects of climate change are social, political, and economic. 73°F WT
