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.
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.
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.
It has become cliché to say that we know more about the surface of Mars than we do about the depths of our oceans, inaccessible as they are to us landlubbers. Nevertheless, technological advances have allowed us to discover more and more about the denizens of the deep. Anyone who has watched Blue Planet II or similar recent documentaries can testify to the bizarre and wonderful life forms that can be found there.
