The phenomenon of “shifting baselines” is, to me, one of the most powerful concepts in ecology, explaining a lot of the damage humanity has wreaked on its environment. Vanishing Fish is a career-spanning collection of previously published essays, with some new material, from the pen of fisheries biologist Daniel Pauly who coined this term in 1995. And when a man like him speaks, I listen. The book gives an eye-opening overview of the state of the world’s fisheries, and the research that revealed the institutional ignorance that partially obscures the gravity of the situation.
American author Paul Greenberg has written two previous books about (eating) fish (American Catch: The Fight for Our Local Seafood and Four Fish: A Journey from the Ocean to Your Plate), so he is no stranger to the rather, errr, fishy topic of omega-3 fatty acid supplements. His new book, The Omega Principle, is much more than just a critique of the supplement industry though. This engagingly written reportage digs far deeper, asking where this oil comes from, and reports on that vast segment of the global fishing industry known as the reduction industry, and a food system out of whack with our needs.
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.
Krill is one of those enigmatic invertebrate groups that feeds whole ocean ecosystems but remains itself little known. Even to a biologist such as myself (who has studied fish for crying out loud!), these critters are largely a set of question marks. I mean they are crustaceans, swim in the sea, are numerous and… oh look, a blue whale!
If I asked you to name the most endangered cetacean species, I doubt the vaquita would come to mind. You might mention the baiji, the dolphin living in China’s Yangtze river, but alas, no living members of this species have been seen for years, despite intense search efforts, and the species is presumed extinct. Unfortunately, the vaquita seems to be next in line. Biologist Brooke Bessesen here tells its sad story, revealing the complex world of species conservation.
I am going to start this review on a tangent. The liner notes of the 1983 album Zeichnungen Des Patienten O.T. of the German industrial band Einstürzende Neubauten contained the slogan “Destruction is not negative, you must destroy to build”. I don’t expect that Ugo Bardi shares my taste in music, but, judging from this book, I’m sure that if we were to sit him down with the band members over a pint, they would have plenty to talk about. Because, according to Bardi, collapse is a feature, not a bug.
It should have been a straightforward expedition. As a young career palaeontologist, Nick Pyenson found himself in the Atacama desert of Chile, tasked with mapping rock layers to establish a continuous chronology that would help dating fossils found in the area. Whale fossils, Pyenson’s speciality, are rarely found complete, which is true of most fossils. So what do you do when a colleague takes you to the construction site of a new highway and shows you not one, not several, but literally dozens of complete fossil whale skeletons? It represented a treasure trove for science, but retrieving the material before the highway constructors would move in was also a daunting, labour-intensive task that could make or break careers. I almost found myself standing next to Pyenson in the dusty clearing, the Chilean sun beating down on me as he faced this dilemma. This is just one of several immersive narratives recounted in Spying on Whales, which successfully blends travelogue and popular science.
Helen Scales is a marine biologist, diver, and surfer, and is no stranger to writing good books. I have previously read Poseidon’s Steed: The Story of Seahorses, from Myth to Reality from her hand. The book after that, Spirals in Time: The Secret Life and Curious Afterlife of Seashells, received critical praise in the press and was shortlisted for the Royal Society of Biology book prize. Here, Scales turns her attention to fish. Is this another page-turner waiting to be recognised?
Brian Fagan is a celebrated archaeologist and author who has written many books on the topic of environmental history. Several of these sit on my shelves, though I admit this is the first book by his hand that I have read. With Fishing, Fagan presents a deep history of fishing from the time of our human ancestors up to the present day, highlighting its overlooked role in the history of human civilization. His story spans the globe and pieces together a fragmented and complicated puzzle.
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.
