Life most likely originated in the oceans, and it is to oceans that astronomers are looking to find life elsewhere in the universe. With the publication last year of Kevin Peter Hand’s Alien Oceans, I decided this was the right time to finally review Ocean Worlds, a book that I have been very keen to read ever since buying it some years ago. This, then, is the first of a two-part dive into the story of oceans on Earth and elsewhere.
Rivers and oceans are easily neglected when it comes to pollution. Out of sight, out of mind and all that. Except that the oceans do not forget. Of all the water pollution problems, oxygen loss is probably one of the more abstract ones. Even the words used to describe it, hypoxia and anoxia, will be meaningless to those without a background in biology. In Dead Zones, marine scientist and microbiologist David L. Kirchman provides a general introduction to the problem of oxygen loss and why it matters.
In his book Half-Earth, the famous biologist E.O. Wilson proposed setting aside half of the planet’s surface for conservation purposes. Deborah Rowan Wright will do you one better; given how important they are for life on the planet, how about we completely protect the oceans. What, all of it? Yes, not half, all of it. We need a gestalt shift, from “default profit and exploitation to default care and respect” (p. 11). Such a bold proposal is likely to elicit disbelief and cynicism—”Impossible!”—and Wright has experienced plenty of that. But hear her out, for sometimes we are our own worst enemy. Future Sea is a surprisingly grounded, balanced, and knowledgeable argument that swayed me because, guess what, the oceans are already protected.
Planet Earth is a somewhat unpredictable landlord. Mostly, conditions here are benign and favourable to life, but sometimes its tenants are suddenly crushed in a violent outburst. For as long as humans have lived, we have been subjected to such natural catastrophes and have been trying to both understand and predict them. As marine scientist Dr Ellen Prager shows here, we have made great strides, but many questions and unknowns remain. Dangerous Earth is a fascinating tour to the cutting edge of the earth sciences to look at some of the complex problems for which we are still lacking answers.
In Algae We Trust. That might just as well have been the subtitle of this book. In Slime (published in the UK as Bloom, but I read the US version), author Ruth Kassinger writes of the many fundamental, often eye-opening roles that algae play in our ecosystems. But she also travels around the world to talk to farmers, scientists, and inventors. From food to plastics to fuel, entrepreneurs are discovering that these little green powerhouses hold immense biotechnological potential.
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.
So, stop me if you’ve heard this one before, but it is often said that we know more about the moon than we do about our own oceans. However, palaeo-oceanographer and climate scientist Eelco J. Rohling points out we know more than you might think. His new book, The Oceans: A Deep History, takes the reader through a 4.4-billion-year history of Earth’s oceans. Much more than just a book about water, this is foremost a book about the intimate link between our planet’s climate and its oceans, as they are far more intertwined than you might give them credit for.
