Ethics on the Ark presents a passionate, multivocal discussion—among zoo professionals, activists, conservation biologists, and philosophers—about the future of zoos and aquariums, the treatment of animals in captivity, and the question of whether the individual, the species, or the ecosystem is the most important focus in conservation efforts. Contributors represent all sides of the issues. Moving from the fundamental to the practical, from biodiversity to population regulation, from animal research to captive breeding, Ethics on the Ark represents an important gathering of the many fervent and contentious viewpoints shaping the wildlife conservation debate.
