Human life

Human life, I believe, is the most precious life on this planet. As such all human beings have the responsibility as well to preserve, nurture, and develop all other species on this planet.in course of thousands of years we have managed to be masters of this planet, bringing under our domain, practically all other species. At the same time we have made thousands of such species extinct. Many others are on the way of becoming extinct. This is breach of trust, pure and simple. Our future generations will ask us why? Have you an answer?
