GE2021 ENVIRONMENTAL SCIENCE AND ENGINEERING(Common to EEE, EIE, ICE, Biotech, Chemical, Fashion, Plastic, Polymer & Textile)
AIM:The aim of this course is to create awareness in every engineering graduate about the importance of
environment, the effect of technology on the environment and ecological balance and make him/her
sensitive to the environment problems in every professional endeavour that he/she participates.
OBJECTIVES: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.
