"Nature has been mercilessly exploited by mankind in various ways for short-term benefits without realizing its consequences. Due to population explosion, rapid industrialization, unplanned urbanization and destruction of natural resources, eco-degradation has made the life of human beings miserable on this watery planet. During the recent years, with the growing concern for the environment and its management, the accumulated scientific concepts on environment have witnessed the emergence of a multi-disciplinary subject, i.e. environmental science. The aim of this book is to provide its readers an acquaintance with recent research trends in the field of environmental science. For this purpose, the present book is a unique compilation of 49 articles contributed by eminent authors with different backgrounds, which will act as a keyboard in opening new vista in the field of environmental science. With its application-oriented and inter-disciplinary approach, the book would be immensely useful to everyone dealing with the environment, such as university teachers, environmental scientists, academics, technocrats, politicians, researchers and post graduate students."
