Increased concern with the environment has increased opportunities for employment in the environmental job market. This digest helps clarify the meaning of environmental employment and discusses aspects of its present state. An examination of trends in environmental employment indicates a growing demand for new jobs in environmental fields created from either remedial actions, such as clean-ups and regulatory actions, or from prevention activities. Growth in other careers such as foresters and conservation scientists is expected to be slow. A classification of jobs in environmental fields is done according to content-focus and position-focus. Content-focus careers include careers in pollution prevention and control, disease prevention, and environmental planning. Position-focus careers include careers in environmental science, environmental policy, environmental information, and related professions. Since environmental science is an interdisciplinary arena, preparation for environmental occupations requires an understanding of biology, chemistry, and the physics of the environment; problem solving and mathematics skills; and preparation in a specific area of interest.
