Conserve and protect

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.

Learn about conserving and restoring ecosystems, and explore issues in environmental governance. And thanks to our small classes, you’ll develop a real sense of community right from first year.

When you graduate, you can apply your knowledge in a growing number of fields, from green technology to ecological consulting to environmental law. And if you want an early start, you can also apply that knowledge to paid co-op work terms.
