This book has been organized according to the syllabi of Environmental Sciences for undergraduate and postgraduate students of different universities and colleges.
The modern ecology and environment have embraced not only old philosophy of live and let live but the very recent tools and techniques required to establish the causes and consequences of the ongoing changes in the environment, which the human kind never realized earlier.
The entitled "A Textbook of Ecology and Environment" is an attempt wherein, the authors have tried to incorporate the old and recent aspects of ecology. It has been the humble attempt of the authors to provide information on the various dimensions added in the modern ecology.
