Mankind: Origin, Journey To The Present And Future (Paperback, Alok Bhattacharya)  (Paperback, Alok Bhattacharya)

Mankind: Origin, Journey to the Present and Future About the Book The pre-historic connection of the African continent with peninsular India in the Gondwanaland day led author to think whether the earliest inhabitants of India came from Africa. The present world view, however, rules it out by assuming that Gondwanaland disintegrated long before the humans arrived in Africa. This view, however, cannot convincingly explain how the primitive Man spilled all over the world in the later years, crossing the huge oceans in between. The present book is an attempt to solve this puzzle on the basis of available evidences. The invention of machines in 18th century by humans, though lauded as the greatest achievement, has also resulted in ever-increasing pollution and destruction of nature in the name of development. The cumulative effect of all this after centuries of progress has brought us to the precipice where global warming and its ugly effects are bringing the planet to the brinks of a catastrophe. The only way to reverse this effect in the author's view is to ascertain that the majority of our population retains agriculture as their livelihood. That is the only way global warming can be reversed. The book is based on rational thinking and scientific reasoning.
