Authors are happy to present the Seventh revised edition of Environmental Studies for F.Y.B.Com. It is an indisputable fact that global environment has a pronounced effect on our lives. Increasingly so is the impact of a degrading global environment due to the burgeoning world population, concomitant decrease in natural resources and the negative effects of globalization and technological development. Apart from its direct impact on the environment, globalization has a bearing on the economic climate and trade patterns. The book is a product of a long period of experimentation with teaching Environmental Studies.
