Get a science degree. Save the planet.
Get a solid grounding in science and geography and still have lots of room to explore environment-related courses in math, ecology, microbiology, hydrology, and more. You’ll learn about climate change, groundwater flow and contamination, environmental impacts of pollution, responsible extraction of Earth resources, waste disposal, and human engineering of Earth processes.
Specialize in Ecology to address ecological sustainability and biodiversity while learning about the fundamental science of life on Earth. Go the Geoscience route and focus on the interactions among the geosphere, hydrosphere, atmosphere, and biosphere as well as the human activities that encompass the complex and dynamic Earth System.
Or specialize in Water Science and investigate the unique properties of water; the distribution and movement of fresh and salt water above, on, and within the Earth; and the quality and quantity of water that humans depend upon to survive and thrive on this planet.
Any route you choose, whether you want to gain paid work experience through co-op or not, you’ll be part of one of the top four environmental science programs in Canada (Academic Ranking of World Universities 2020) — and graduate with the scientific knowledge, creativity, and expertise you need to create a more sustainable world.

Customize your Environmental Science major
For any of the specializations, you can choose electives from many of the 100 subject areas at Waterloo.
You can also add additional areas of expertise to your degree by including one of the minors or diplomas available to all Waterloo students. Popular areas of focus for Environmental Science students include Biology; Earth Sciences; Chemistry; and Environment, Resources, and Sustainability.
What can you do with an Environmental Science degree?
Your career path will really depend on your interest. If you're very interested in a specific topic, you might continue on a specialized Master's degree. You can also go directly into your career in fields such as environmental or ecological consulting, industry (such as engineering firms), government research, and not-for-profits. Management of resources, particularly water; policy and legislation; environmental conservation and remediation; and environmental monitoring are some potential career areas.

How is Environmental Science different from programs in the Faculty of Environment?
Environmental Science takes an analytical (and science-based) approach to understanding systems and interactions in the environment. Programs in the Faculty of Environment focus more on social science and impacts to people and communities. Faculty of Environment programs are ideally suited to policy, decision making, and government whereas Environmental Science often focuses on environmental processes and the impact of human-related activities on the natural environment.
