There are three chapters on whaling, the first covering the early period, the second the period of mechanisation and industrial scale whaling, and the third the modern era of the International Whaling Commission and the rise of conservation concerns.
Two chapters address other threats to dolphins and whales from humans: accidental death or injury from fishing, noise pollution, climate change, and pollution. And two chapters cover less negative interactions: the controversy over keeping whales and dolphins in captivity, debates over cetacean intelligence, the rise of whale-watching and swimming with dolphins, and the difficulties involved in establishing marine sanctuaries.
Troubled Waters is a simple and straightforward overview. But it offers a balanced perspective on an often controversial topic, eschewing drama or hyperbole and allowing the natural fascination of the material to shine through. I recommend it to anyone who wants a short, accessible history of human-cetacean relations.
