The book will be immensely useful to all categories undergraduate students, including those with inadequate bioscience background. This will also be beneficial to students appearing for competitive examinations. Salient features: Meant for undergraduate qualifying course on environmental studies prescribed by UGC. Matter split into 8 units spread over 54 chapters for comprehensive and synchronised coverage. Subject analysed in simple manner with up to date information, each chapter independent and inter linked. Well supported by adequate illustrations and case studies.
