A comprehensive text book for the students of law on Environmental Law, contains various chapters dealing with Environmental Problems and Policies, Environmental History, Environmental Protection & Constitutional Obligation, Natural Resource Conservation Laws, Animal Welfare Laws, Legal Remedies for Environmental Problems, Civil Societies & Environment, International Environmental Law, Region Specific Environmental Problems etc. etc. We know very well that the earth does not belong to man but man belongs to the earth. Whatever befalls the earth befalls the sons of the earth. Wordsworth said: "Nature never did betray that heart that loved her". Pythagoras added by saying, "For so long as man continues to be the ruthless destroyer of lower living beings, he will never know health or peace. For so long as men massacre animals, they will kill each other. Indeed, they who sow the seeds of murder and pain cannot reap joy and live."""To reap joy and lead a healthy life, one needs to have a clean and healthy environment all around. The activities of persons which have impact on "environment" needs to be regulated and hence, 'Environmental Law' has emerged as one of the most important tool for protection, conservation and management of environment and its resources, while promoting development without destruction. There prevails a general opinion that there are no standard and comprehensive textbooks available on this subject, which has been included in the curriculum for legal education recently. The Books that are available now are either commentaries or critiques on the subject. The book contains an interesting analysis of the subject, which will certainly create an interest in learning the subject in depth and will cater not only to the requirements of the students of law but will also be useful for the Bench and the Bar as an introductory book containing summary of cases decided by the Supreme Court and High Courts on environmental issues. Apart from the legal fraternity, the book will also be of immense help to NGOs, environmentalists and other environmental law enforcing agencies.
