Gettysburg College has defined sustainability as: the human-environment interactions that allow current and future generations to meet their needs in socially just, economically viable, and ecologically sound ways. This definition hints at the inherently interdisciplinary nature of  sustainability.

With such a broad and wide-reaching definition, courses spanning over multiple disciplines focus on issues of sustainability.
