What does the deep ocean make you think of? An alien world right on our doorstep? The cradle of life? A global garbage dump? The lungs of the planet? Or the world’s most abused ecosystem? If I am to believe marine biologist Alex Rogers, the deep ocean is all of the above, and so much more. With three decades of research experience and scientific consultancy credits for the BBC series Blue Planet II under his belt, he knows what he is talking about and he knows how to talk about it. The Deep is an intensely captivating and urgent book that swings between wonder and horror.
Speaking of controversial. As mentioned in my previous review of An Essay on the Principle of Population: The 1803 Edition, concerns about human overpopulation go back to at least Malthus, a name that has become synonymous with this topic. How do you tackle this incredibly thorny issue? Malthus believed moral restraint where having children is concerned should be encouraged, which strikes me as starry-eyed and completely out of reach, especially in the individualized societies of today. Simultaneously, we have seen some pretty drastic population control measures with ugly side-effects, such as China’s one-child policy and forced sterilization in India. The cry of eugenics if never far away when this topic is tabled. Can we have any sensible discussion to find a middle ground between utopia and dystopia? This small book does a serious attempt.
Following hot on the heels of Cambridge’s Defending Biodiversity: Environmental Science and Ethics, Oxford University Press has just published the edited collection Effective Conservation Science: Data Not Dogma. Whereas the former title was careful about courting controversy, a quick scan of the chapter titles of this book suggest it is seeking out hot-button issues sure to upset some people (“Uncomfortable questions and inconvenient data in conservation science”, “Introduced species are not always the enemy of conservation”, or “Rehabilitating sea otters: feeling good versus being effective”). Together, these two books form an excellent combination of a philosophical and pragmatic examination of biodiversity conservation, and how we could do better.
Perhaps more than any other discipline, conservation science arouses strong feelings of righteousness, of fighting the good cause. Critical questions or results that run counter to the narrative of nature-in-decline are unwelcome, often out of fear that policy makers and the media will misinterpret such findings, leading to drastic reduction in support for conservation efforts. Though understandable, Effective Conservation Science is a collection of 26 cautionary tales of the dangers of such thinking.
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.
