The environmental sciences (ES) major is designed for students who have a keen interest in ecology and the interactions between humans and the natural world. Environmental sciences majors take a wide variety of science and non-science courses. In fact, environmental science majors are the most broadly trained of all science majors at Notre Dame. Further, those majoring in environmental science also have great latitude in their course choices. This freedom to specialize is one of the key features of the environmental sciences major.
