Colby offers majors in environmental science with an emphasis in one of three departments in the Division of Natural Sciences: biology, chemistry, or geology. Each of these interdisciplinary programs is designed to prepare students for roles as educated citizens in a world increasingly confronted with environmental problems, for graduate study in the environmental sciences or related disciplines, and for entry-level positions with consulting firms, government agencies, or non-governmental organizations.

Environmental science concentration in biology
A major program that includes work in biology, physical sciences, and social sciences. Instruction in ecology and environmental science includes a survey course in ecology that introduces students to a variety of Maine ecosystems and a junior-year course in ecological theory that offers a detailed review of ecological concepts and their relevance to environmental issues. A senior practicum enables students to apply the concepts they have learned to an environmental problem of local significance.

Environmental science concentration in chemistry
Students electing this major complete all the courses required for the chemistry major. In addition, two courses are required in biology and economics. Chemistry 217, Environmental Chemistry—which discusses the application of chemical principles to such topics as fates and toxicity of heavy metals and organic pollutants in soils and natural water systems, corrosion, complexation, and analytical techniques—is required, as is an independent study.

Environmental science concentration in geology
An environmental concentration focusing on energy and water issues. Requirements include selected courses in biology, chemistry, mathematics, and economics, in addition to a core of geology courses. An independent project course serves as a culminating and integrating experience in the senior year.

Each of these environmental science majors emphasizes the scientific foundation that must underlie environmental planning and decision making. Specific requirements for each concentration are listed in the departmental sections of this catalogue. Students are also encouraged to complement their work on campus with January Programs and other off-campus educational opportunities, including affiliated programs offered by the School for Field Studies and the Woods Hole Oceanographic Institution.
