For a decade and a half, this book has been considered the most reliable textbook on the subject for all undergraduate students. This third edition has been revised as per the new AECC syllabus set down by the UGC and has been made extremely user-friendly. The aim of this edition is not only to create an awareness of environmental issues, but also to bring about pro-environmental action. The new, two-colour design of this edition will appeal to students and aid in reading and retention. The unique feature of this textbook is the accompanying App containing additional questions, colour pictures and video lectures.
