What's So Good About Biodiversity?

This unique exploration of biodiversity breaks down the distinctions between science and economics, dissenting from the prevailing view in challenging the widely cherished assumptions that underpin the seemingly unassailable arguments of environmentalists.

There has been a deluge of material on biodiversity, starting from a trickle back in the mid-1980's. However, this book is entirely unique in its treatment of the topic. It is unique in its meticulously crafted, scientifically informed, philosophical examination of the norms and values that are at the heart of discussions about biodiversity. And it is unique in its point of view, which is the first to comprehensively challenge prevailing views about biodiversity and its value. According to those dominant views, biodiversity is an extremely good thing so good that it has become the emblem of natural value. The book's broader purpose is to use biodiversity as a lens through which to view the nature of natural value. It first examines, on their own terms, the arguments for why biodiversity is supposed to be a good thing. This discussion cuts a very broad and detailed swath through the scientific, economic, and environmental literature. It finds all these arguments to be seriously wanting. Worse, these arguments appear to have consequences that should dismay and perplex most environmentalists. The book then turns to a deeper analysis of these failures and suggests that they result from posing value questions from within a framework that is inappropriate for nature's value. It concludes with a novel suggestion for framing natural value. This new proposal avoids the pitfalls of the ones that prevail in the promotion of biodiversity. And it exposes the goals of conservation biology, restoration biology, and the world's largest conservation organizations as badly ill-conceived.

An entirely unique treatment of biodiversity Breaks down disciplinary walls, joining philosophy with hard science and economics Meticulously crafted, scientifically informed examination of the central norms and values The only comprehensive dissent to the view that biodiversity is good Extremely timely as biodiversity is claimed to justify most conservation projects today Offers a novel alternative to capture our intuitions about the value of natural world

This book is unique in its treatment of biodiversity, which has come to be an emblem of what is worthy of protection and fostering in the natural world. It undertakes a comprehensive, detailed, and careful philosophical analysis of the many reasons that scientists, economists, philosophers, and others offer for why biodiversity is supposed to be such a central good of nature. Its conclusion is both surprising and disturbing: No reason for biodiversity's good can be found that is not ill-conceived, logically indefensible, internally contradictory, or self-undermining.

The profound failure to find the good of nature in its biodiversity is a springboard for rethinking what, exactly, makes the natural world so uniquely and robustly valuable. This leads to a novel suggestion that nature's value might be located in a particular human-nature relationship, which anchors the appropriate fit of people in the world at large. Understanding nature's value in this way has far-reaching consequences, which call into question common orthodoxies of conservation, restoration, and environmentalism generally.

"In 1985, Michael Soulé, considered by many to be the father of the academic discipline of conservation biology, laid out his four normative postulates for the field: diversity of organisms is good, ecological complexity is good, evolution is good, and biotic diversity has intrinsic value. In this book, Don Maier provides an essential, lucid, and critical evaluation of these claims. It is a must read for all who seek to conserve the diversity of life."

"It's widely claimed that biodiversity is valuable. But to date, there has been little systematic, critical scrutiny of this claim. Don Maier's What's so good about biodiversity? boldly undertakes this task. After carefully examining a variety of arguments for the value of biodiversity, and expressing serious doubts about where the valuation of biodiversity leads, Maier concludes that Biodiversity is the wrong hook on which to hang the value of nature. Not content with a purely negative project, Maier then proposes his own, thought-provoking account of natural value. Maier's book will stimulate readers to scrutinize and reassess their own beliefs about value in nature. His book will make a significant contribution to environmental ethics, and to broader debates about the ultimate goals of environmental conservation."
