Within the natural sciences, environmental science is very much a generalist degree. Focusing primarily on both the understanding of our natural and man-made environments, environmental science degrees draw from diverse fields of studies and require a strong background in the more traditional sciences: biology, physics, chemistry, geography, and ecology. In addition, environmental science degrees also draw heavily from the social sciences, such as economics, business, or sociology. The degree to which any of these fields of study becomes prevalent within an environmental science education largely depends on the specialization one chooses. Due to the fact that environmental science is a generalist degree, students often complete specializations within a more select area, i.e. energy, sustainability, conservation, etc. True to most science degrees, environmental science programs often require significant field work, lab work, or other data-oriented work.
