Environmental decisions are frequent and important in our daily lives, ranging from personal behavior to international policy. Students in Environmental Studies learn about modern environmental science in the context of contemporary global issues, exploring the impact that the decisions of nations and individuals have on local and world ecologies. The course emphasizes the science involved in environmental decisions while also examining the roles of ethics, politics, and economics in all real life environmental situations. Students examine such topics as ecology and biodiversity, including the nature and effects of succession, evolution, and invasive species; the atmosphere, including air pollution, ozone depletion, and climate change; sources, use, and misuse of water resources; human population and feeding the world’s people, including developments in agriculture and genetic modifications of organisms; and the nature of earth’s energy resources and their use by humankind. Additionally, they explore the impact that environmental decisions have on cultures around the world, investigating global issues such as biological conservation, human population growth, chemical and biological technologies, and environmental justice.
