Webster's 9th Collegiate Dictionary defines Environment "... as the complex of physical, chemical, and biotic factors (such as climate, soil, and living things) that act upon an organism or an ecological community and ultimately determines its form and survival".
Both human and physical geography provide an important intellectual background for studying the environment. Many environmental studies/science programs offered by Universities and Colleges around the world rely on the information found in various geography courses to help educate their students about the state of the environment.
