Environmental Science (BSc)

Joint program with the Faculty of Science

While Environmental Science is a broad technical field – integrating biology, chemistry, physics and physical geography – it includes the essential work of understanding the impact human activities have on our planet.

Students explore these critical issues:

  • Climate change impacts and adaptation
  • Biodiversity and conservation of species and habitats
  • Water security and water quality
  • Pollution
  • Erosion
  • Environmental hazards

Through your studies, you will get practical experience in data collection, research, and scientific analysis in the field and in the laboratory. You will learn to work collaboratively and develop effective communication, analytic and critical thinking skills while better understanding climate, ecological and biophysical systems.

Our environmental science students gain a scientific foundation in the biological and physical sciences needed to address urgent environmental and urban challenges – and generate and communicate solutions.

You’ll choose one of two streams. Students in the Biodiversity & Conservation stream will specialize in environmental biology to understand how organisms and ecological communities are impacted by environmental stressors and learn to apply this knowledge to protect species and biodiversity. Students in the Environmental Change stream will specialize in physical geography, studying the interactions between land, air, water, and biological organisms to understand how the natural environment responds to stressors.
