Environmental Biology

banner stating "environmental biology"

How does climate change affect the earth?

Environmental Biology within the B.Sc. degree program will focus on how organisms, such as plants, insects, fungi and bacteria interact with the physical environment, including water and soils, as well the impact and response to human activity.  

What's Unique?


The Honours B.Sc. major in Environmental Biology is offered by the School of Environmental Science. This major is highly flexible and allows students to design their own focus within the field.

Program Details 

In this major you will learn about biological diversity or plants, insects, fungi and bacteria at the molecular, population and community levels. Methods of measuring and monitoring the impact of human activities on natural and agricultural ecosystems will be presented. To counter negative impacts, solutions, such as bioremediation of effluent, waste management, restoration of stream quality, and agroforestry will be applied. Upon graduation, you will have an awareness of the social and economic implications of environmental bio-sciences and be prepared to initiate solutions for a diversity of environmental problems.
