CSES Professor and student

Overview

    This program brings the basic sciences to bear on many crucial concerns about the environment. The environments of particular interest are terrestrial and wetland ecosystems and associated land and water resources. Specific concerns include environmental protection, pollution prevention and remediation, land-use planning, waste management, ground- and surface-water quality, reclamation and remediation of disturbed or contaminated sites, and minimizing human impacts on the environment.

    The Environmental Science curriculum is multidisciplinary and strongly science and technology oriented. The basic sciences and computational skills are at the core of each of the major's three options, but specific requirements make each option unique. The curriculum prepares graduates for immediate entry into environmental careers as well as for graduate specializations. The U.S. Bureau of Labor Statistics forecasts that employment of environmental scientists and specialists is expected to increase by 28% between 2008 and 2018, much faster than the average for all occupations.

    The three concentrations, or curricular options, within the major and example of the career opportunities within each are as follows:

Water Resources Option

    The emphasis in this option is on fresh water systems and resources, although there are obvious connections to esturine and marine settings. Both surface- and ground-water quality may become degraded as a result of human activities. Those processes, their consequences, and solutions are the focus of this option. Students in this option are entering careers in the areas of regulation, remediation, and environmental protection.

Land Resources Option

    This option develops an understanding of many of the complex biological, chemical, economic, geological, and soil factors that affect land use decision-making. Because our strategy of handling waste is often to "dump it in a hole", this curriculum also deals with issues of waste management and environmental clean-up. The graduates in this option find employment with various governmental agencies and in the private sector.

Plant Resources Option

    This option provides a track for students seeking environmental careers that build on their interest in plant sciences. Plants are used in a variety of ways to solve environmental problems. For example, reclamation of disturbed areas often involves establishing and managing adapted vegetation. Plants are important components of wetlands, which provide a number of important environmental functions and values. Plants are also used to remove pollutants from the soil or water.

Opportunities to Excel

    Students with outstanding records can qualify for the Honors Program and graduate "in honors" in environmental science. Other opportunities for personal and professional growth and for recognition include the department-sponsored Environmental Student Organization, membership in Alpha Zeta and other honoraries, and several scholarships designated for majors. Faculty members often offer undergraduates opportunities to become involved in a variety of environmental research projects. Many employers seek environmental science majors for internship and co-op positions.
