The aim of thecourse is to make everyone aware of environmentalissues like continuing problems of pollution, loss offorest, solid waste disposal, and degradation ofenvironment. Issues like economic productivity andnational security, global warming, the depletion ofozone layer and loss of biodiversity are other seriousconcerns before the mankind.1. THE MULTIDISCIPLINARY NATURE OFENVIRONMENTAL STUDIES: Basic definitionsrelated to environment; Scope, vis-à-visenvironmental science and environmentalengineering; Causes of environmentaldegradation, atmospheric composition andassociated spheres, habitat and climate; objective,goals and principles involved in environmentaleducation, environmental awareness,environmental ethics, environmental organizationand their involvement.2.
