Your Four-Year Journey
Year 1: Understanding
In your first year you will take Introduction to Environmental Science and discover that, at the college level, ESS is far more interdisciplinary than AP Environmental Science. The class covers agriculture, conservation, energy, and climate change but also teaches you to use art, psychology, ethics, politics, and economics to complement what you know about science. Life Cycle Analysis and patterns of consumption take center stage. Assignments include providing solutions to environmental challenges on campus and in the community.
Year 2: New Approaches
This is the year that ESS classes enhance your ability to think, read, speak, and write critically (ENVSC 270) and engage methods used by ESS professionals to solve environmental problems (ENVSC 210). You will begin to explore classes and internships to complement your ESS classes. Approximately one-half of classes for the ESS major are electives students choose after consulting with their faculty advisors.
Year 3: Delving Deeper
Year three is when you become an ESS professional. The Junior Seminar in Sustainable Development (ES 585) comes together with study abroad, internships, research opportunities, and classes from around the College and around the world as you develop into a global thinker and actor.
Year 4: The Comp
Time to select the project you care most about to spend a year on it with your faculty advisor. Almost every student reports back that their ESS Senior Comp was the most satisfying thing they did at Allegheny College. You can even show your Comp to prospective employers!
