Environment has become one of the major concerns of today’s life. In the urban areas especially in metropolitan cities, pollution is found in various forms. Air-pollution, water-pollution, sound-pollution and chemical-pollution are the issues that create a lot of health problems. Keeping in view the importance of environment almost all the education boards, universities and institutions have included environmental studies as one of the subjects of study. To provide the broad knowledge of Environmental studies, Dr. R.S. Shrivastava has developed very systematic contents not only to students but also to general readers. Bio-chemical cycle, Bio-Geo chemical cycle, Solid Waste Management, Plastic Waste Management, Genetically Engineered Foods, Water Wars in 21st century, Ecological Globalization, Narmada Dam Projects, Neem– the wonder tree, and ‘B’ Urja for Rural Development are the highlights of the book. Tabulation, charting and figure works make the book very appealing.
