This book is about the disastrous effects of environmental pollution and climate change not only on the human race but on the whole ecosystem existing on this Earth including the Marine ecosystem. The problem is impending and the worst part is that we are still brooding over various pros and cons of it, instead of acting in right earnest. Within the comity of nations, there is no consensus regarding the enormity of the problem nor about the measures to be taken. How to bring all the Nations on one platform is a big challenge. At present, many countries of the world are facing acute water shortage. The crux of the issue is proper water management which is entirely lacking in many countries including India. This problem, if not attended timely, will escalate globally culminating into war among Nations. Climate justice is as crucial as social justice. It is a pity that there is no international court of justice type institution for environmental pollution cases. The purpose of the book is to enlighten the reader about the most horrendous problem of our Times. The existence of the whole human race is in jeopardy.
