Environmental Sciences




The Program in Environmental Sciences offers one 3-credit course at the 100-level (see course description at the bottom of this page):

ENSC 115 - Introduction to Environmental Science

This introductory course is normally a first-year requirement for students planning an advanced major or honours degree in environmental sciences.  However, this course is not being offered in the 2017-2018 academic year.  For this year, students in most streams will take BIOL 111 instead of ENSC 115; those following the Climate and Water stream will take ESCI 171 as a replacement for ENSC 115.


Environmental Sciences is a purely interdisciplinary program, meaning that all courses associated with it are relevant courses from other academic subjects (besides ENSC 115; a non-credit fourth-year seminar; and, for honours students, a 3-credit honours thesis course).

There are four different concentrations from which to choose: Biology; Chemistry; Biogeochemistry; Climate and Water.

There is a core group of courses common to all concentrations. Those core courses are distributed throughout the years of the program, but are primarily concentrated in the first two years.

The first year of the program is the same for all concentrations, with a slight difference for the Climate and Water stream. Please see the Bachelor of Science with Major program page in Step 2 for more specific course information for first year. (See “Environmental Sciences” under the “Science Courses” heading.) This course information can also be found in the Academic Calendar.


Course Description from the Current Academic Calendar: 

115   Introduction to Environmental Science
Environmental science integrates our understanding of chemical, physical and biological processes to study how anthropogenic activities have altered natural environments. The focus of this course is upon the underlying processes that drive environmental change, e.g. environmental contamination, water resources, biological diversity, global climate change, food production, and deforestation. By developing an understanding of the complex scientific processes that drive environmental changes, students will acquire skills that will equip them to identify solutions to environmental problems. Three credits and lab.
