Orcas or killer whales have been at the centre of a swirling controversy for decades. Popular attractions in aquaria, their plight there has been highlighted in recent books and documentaries, further strengthening opposition to keeping cetaceans (i.e. whales, dolphins, and porpoises) in captivity. However, as Jason M. Colby meticulously documents in this book, there is a cruel irony at play here: this very practice of captivity is what raised our environmental awareness in the first place.
Most people would agree that it is important to conserve wildlife and the environment it lives in. But can you clearly articulate why? Defending Biodiversity brings together an ecologist and two philosophers to critically examine the arguments environmentalists often put forward in favour of biodiversity conservation. Because, as they point out, a lot of these arguments are not very strong, and sometimes conflict with each other, or with other parts of what environmentalists wish to achieve. Now, before you get all worked up, all three authors strongly believe that biodiversity ought to be conserved, and this book is not an attack on environmentalists or biodiversity conservation. They are careful to avoid being unnecessarily controversial with this book. Rather, they want to help environmentalists improve and strengthen their arguments and to become more persuasive in debates.
