In order to culture healthy environment on planet earth there is need to protect natural environment at individual, national and international levels. The entropy of biophysical environment is under constant transformation due to advancements in science and technology. Global awareness is required to put a check on progressive environmental degradation.
New academic disciplines, such as Environmental Studies, Environmental Management and Environmental Engineering have been introduced to study and preserve the natural environment in a systematic scientific manner. Concurrently, the main global environmental issues are pollution caused by human actions, bio-extinction, and some geo-matereological changes.
