The book- 'Environmental Education: Principles and Policies' in its tangible form is the result of exhaustive research on each of the topics, innovative ideas, and overwhelming response from the student community to my earlier book on this subject. The book will act as self instructional study materials and help graduate and post graduate level students of various universities of India and abroad to prepare for their examination without much support from their teacher. This book is also expected to help individuals to explore environmental issues, engage in problem solving, and take action to improve the environment as informed and responsible citizen.
