The living world needs champions. Ready to start training?

Use insights from the natural and social sciences to help solve some of the world’s biggest environmental and sustainability challenges — from water scarcity to pollution to loss of biodiversity.

Integrate ecology and social science and connect practical skills in ecosystem monitoring and restoration with environmental policy analysis, impact assessment and collaborative decision making. Belong to a community of professors, co-op employers, and classmates committed to making positive change.

When you graduate, you can apply your knowledge in a growing number of fields, from green technology, ecological consulting, and environmental law to being a terrestrial and wetland ecologist, sustainability policy analyst, parks and protected area manager, or an environmental educator.
