Environmental Sciences degree information

What is Environmental Science?

Environmental science is the study of the natural environment and its processes and interactions, including how humans impact and interact within the environment. The objective is to improve the current and future welfare of humans through the application of science and the development of sound environmental policies.

Why Study Environmental Science?

Over time, people are becoming more aware of the importance of monitoring and protecting the environment in which we live. We are realizing we have a significant impact on the natural environment around us, and global population growth is increasing the demand for positions in the environmental science field.

An environmental science degree is versatile, allowing graduates to be employed in a wide range of fields and sectors including private, non-profit and government agencies. As an environmental science major, your courses will involve problem-solving studies related to water and soil quality, economics, environmental policy, political science, resource management and engineering. In addition, you will gain important skills in communication, philosophy, ethics and sociology.
