To  create   awarenes in  every  engineerin graduat abou th importanc of environment,  the effect of technology on the environment and ecological balance and make them sensitive  to the environment  problems  in every professional  endeavour that they participates.

At the end of this course the student is expected to understand  what constitutes  the environment,  what are precious resources in the environment, how to conserve these resources, what is the role of a human being in maintaining a clean environment and useful environment for the future generations and how to maintain ecological balance and preserve bio-diversity. The role of government and non-government  organization in environment managements.
