Dolphins and whales are a "mind in the waters", with self-awareness, culture, and complex communication. But they, and their cousins the whales, are under threat almost everywhere from hunting, entanglement, habitat damage and toxic pollution. This book puts Dr Mike Bossley's research and activism into an international perspective on the campaign to protect these enigmatic beings. This book describes Mike's epiphany watching dolphins bodysurfing with humans and goes on to describe his work in helping stop whaling in Australia and then reducing it worldwide, and how, as one of the founders of Greenpeace International, he helped the organisation evolve from a scattered band of eco-anarchists into the most powerful environmental organisation of the twentieth century. Along the way Mike Bossley has survived the attempted assassination by French commandoes who bombed the Rainbow Warrior in Auckland harbour; turned an ecological slum into an internationally respected dolphin sanctuary; befriended a lonely hermit dolphin and performed psychotherapy on him; and documented the emergence of cultural behaviour in Adelaide dolphins. In many ways the situation is gloomy, but Mike Bossley hopes this book will inspire people to make a better world for dolphins, whales and all their oceans, and in so doing, to make a better world for all of us.
