I read a lot of natural history. I enjoy it a great deal, and I find it gives me perspective on my own place in the world. I rarely close a natural history book in tears. This one had me weeping numerous times both in despair and in hope. There were times, reading Safina's lucid prose, when I thought perhaps the only thing we could do to save the turtles was to spread some targeted virulent human plague amongst ourselves. There were other times that the stories he told of conservationists made me proud and almost abashed to feel myself part of the species.So. A masterful book which taught me much about the great oceangoing Leatherback turtle and garnered much edifying bycatch along the way. Highly recommended.
