Book review – Catastrophic Thinking: Extinction and the Value of Diversity from Darwin to the Anthropocene

7-minute read

The idea that extinction is a bad thing and diversity a good thing seems self-evident to us. But, by surveying more than two centuries of scholarship, science historian David Sepkoski shows that this was not always the prevailing belief. Rather than a book discussing mass extinction, Catastrophic Thinking is more meta than that, discussing how we have been discussing mass extinction. So, we have an interesting premise, but also an interesting author because – bonus detail – the work of his father, J. John (Jack) Sepkoski Jr., was instrumental in recognizing the Big Five mass extinctions. I could not wait to get to grips with this book.

Book review – Future Sea: How to Rescue and Protect the World’s Oceans

7-minute read

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.
