Half-Earth: Our Planet's Fight for Life

by Edward O. Wilson

Hardcover, 2016





New York : Liveright Publishing Corporation, 2016.


"In order to stave off the mass extinction of species, including our own, we must move swiftly to preserve the biodiversity of our planet, says Edward O. Wilson in his most impassioned book to date. Half-Earth argues that the situation facing us is too large to be solved piecemeal and proposes a solution commensurate with the magnitude of the problem: dedicate fully half the surface of the Earth to nature."--Amazon.

Got every reason Earth to be mad

Edward O. Wilson is angry, and so is his book. No one is listening and things have gotten unbelievably worse. There’s no evidence to provide any real hope. He describes future paleontologists easily identifying the sedimentary layers of our era by the amount of
Show More
chemicals and plastics in the soil strata, by the fragments of machines and weapons everywhere, and the lack of varied species identified. This is our legacy.

As I have written elsewhere, it took the Earth four billion years to reach the Holocene, an era where climate, ice, water and life achieved a state of pleasant equilibrium, with jet streams and ocean currents arranged in a virtuous circle. In just the last 150 years, Homo sapiens has upset the entire system, killing off the Holocene in favor of the Anthropocene, in which one invasive species rules, and any other species that does not add to its immediate benefit can be eliminated. And if even if it does add to its benefit, if it hasn’t been domesticated, it can still face extinction. We are clear-cutting the biosphere.

The book is a relentless, hardhitting – make that pounding – indictment of our custodianship. We are far worse than negligent; we are malevolent. We think it does no harm to remove a species from its environs – and its role. The way it really works is there are no species living on the periphery; every species depends on other species or is critical to the survival of others. Our total disregard of this simple rule causes disaster.

Wilson has been a naturalist all his long life, and it pains him to find things in this state. His childlike appreciation comes through, often overtaking his anger with the wonder of various species and how they live and contribute so differently. That we lose them daily before we even know how they fit in is criminal to him.

Wilson has introduced me to an ugly new subspecies. I will call it the Anthropocene Apologist. AA appears to be a subset of scientists and ignorant people whose attitude is yes, we’ve already wrecked this planet, so let’s just take what we want now and not worry about it. AAs say we should welcome all the invasive species because they fill gaps left by species we made extinct. That they will figure out what to do about the mess when the time comes. It infuriates Wilson. He keeps bringing it up in different contexts, probably because after a lifetime of watching the degradation, he can’t believe there are actual AA scientists promoting it.

His solution is to set aside far more than the 15% now dedicated to wilderness areas and parks. He says we need 50%. This is obviously not going to happen, as populations explode at the same time as land mass disappears (in the rise of the oceans), and less of what’s left is habitable. The book ends very weakly with a plea: Do no further harm to the biosphere.

“…[O]nly by committing half of the planet’s surface to nature can we hope to save the immensity of life-forms that compose it.”

In Half-Earth, American biologist and Pulitzer prize winner E.O. Wilson gives a well-researched, well-documented, eloquent, but above all, impassioned plea on
Show More
behalf of our planet and all of those who call it home, human and non-human alike. Species are dying out at an alarming rate and it is Wilson’s contention that “only by setting aside half the planet in reserve, or more, can we save the living part of the environment and achieve the stabilization required for our own survival”.

Wilson points out that thanks to our behaviour in just the last two centuries, we are now approaching the Anthropocene, a period created by us at the expense of other species. He gives some very interesting counterpoints to those who would argue that this Anthropocene Epoch is now inevitable; that it is really too late to stop completely the march to extinction and we should put all our energy and resources to saving those species who are most useful to us, that in the end the system will right itself. But, as Wilson shows, nature is a complex system in which species depend on each other for survival. To allow the end of even the tiniest mollusk for example can lead and likely will to the end of species that were dependent on it for sustenance starting a chain of extinctions eventually leading to us. Wilson has a more appropriate albeit emotional name for this period, the Eremocene or the Age of Loneliness.

Clearly, Wilson believes that it is time that we stopped seeing ourselves as rulers of the planet and became instead better stewards. He shows clearly and concisely how overpopulation and growing lack of arable land and water rather than religion or historical injustice are driving many of the problems we are facing today in eg the Middle East and, if nothing is done and soon, these problems will only get worse.

This book was both fascinating and eye-opening for me. I found the science enlightening and Wilson’s obvious love and wonderment at the beauty and complexity of nature moving. It was only at the end that the book shows weaknesses. When it comes to the question of how these half-earth reserves are to be achieved, he points to technology but he never really addresses how, in this age of perpetual growth, Anthropocene worldview, and climate change denial, the resolve to make the sacrifices that will be necessary can be achieved. Still, he makes it clear that, if we wish to continue on this planet, we must find ways to do so. As he points out in his final sentence:

“It is simple and easy to say: Do no further harm to the planet. “

Edward O. Wilson succinctly explains the issues facing us today – notably the destruction of the planet and extinction of species. We are in the Anthropocene, the era of humankind’s influence on the planet. We cannot escape the fact that humankind has altered the planet, but Wilson offers a

solution that could solve these problems. Setting aside half the Earth as a resource for the other organisms with which we share this orb is an elegant solution that may be the only way to preserve any biodiversity before it’s too late. Wilson’s book is, as always, full of his signature wit and extensive knowledge of biodiversity. I highly recommend this book to anyone who cares about our planet.

Wilson paints a picture of Earth and it's future that is sad and disheartening while also sounding hopeful and optimistic themes. He is recognized as one of the world's preeminent scientists. His long career in science as well as his life-long commitment to conservation make his positions valid and
Show More
impactful on a world wide basis. While this is not an easy read it was well worth it. Anyone interested in nature, the future of our biosphere, and conservation should elevate this book to "must read" status - BUT - reading is not enough. This book is a call to action and involvement. We should all seek out ways to contribute (words and deeds) to our fragile global biosphere.

Human activity is causing extinctions and rapid change to ecosystems. We all knew that already. What may be a revelation to some readers is how little we truly understand about what it is we are doing or what the results might be. We can only estimate the number of species we have driven to
Show More
extinction because we still don't have anywhere near a complete account of all those that exist today. We can be reasonably certain that this list will be shorter tomorrow, however.

Our understanding of how all these species interact with each other and their environment is also incomplete. Local ecosystems and the larger biosphere seem intricately balanced, so sudden changes can have unforeseen and catastrophic consequences. One of the species we drive to extinction may be our own.

In this book, Wilson argues that our knowledge must be expanded. But at the rate species are disappearing, we won't be able to accomplish anything approaching a complete understanding before many species and their habitats disappear. He suggest that human development be restricted over 50% of the planet, specifically from those places that still can be returned to a state in which they existed prior to human encroachment.

My first reaction to this was, "Yeah, great idea, but that ain't going to happen." Wilson, however, suggests that it might. With just a bit of regulation, and with technological, economic, and cultural changes already underway, humanity is likely to become less wasteful. We will engineer and grow more nutritious crops in vertical farms, which require less land to feed a population that, he says, should stabilize at around 10 billion people. We will use fewer natural resources and use them more efficiently. We will draw our energy from renewable sources....

Well, maybe. Our species is capable of cooperation, reason, and foresight. Sadly, our capacity for aggressive competition, greed, and blind stupidity often gets in the way. We'll see which prevails in the coming years.

Incredibly depressing but a very worthy must-read. Highlights included the list of natural history ecosystems worth saving and visiting. Weakness: The last chapter, an odd discourse on biotech and artificial intelligence.

Songwriter Paul Simon, who leafs through books for inspiration ("Rene and Georgette Magritte With Their Dog After the War"), name-checks conservationist Edward O. Wilson on tour. I can imagine Simon browsing randomly through this volume. Among the lithographs of plants and animals are Wilson's

musings on taxonomy, rare birds and beasts, UNESCO heritage sites (he elides whether the wild horses grazing in the Białowieża Forest are the extinct tarpan) and the folly of assuming we can science our way out of monoculture risk. His cause is a vast expansion of the world's nature preserves, but his plan seems simply to share his enthusiasm for the natural world. Works for me.

Wilson's entirely sensible and probably over-ambitious manifesto in favor of setting aside half the world's surface as a preserve. Perhaps not written for the right audience, unfortunately.

I was somewhat disappointed in this book. The first 2 sections are wonderfully written and I highly recommend the book on the basis of these two sections. The book falls short in the third section. It is a call for action in response to climate change; however, it really falls short especially

after the release of the latest climate report.

I think most of the problems with this book have already been pointed out in previous comments. That said, and having read several of Wilson's books previously, I was hoping to find a well-structured message for, and specially for, the people who have the power or influence to make and change
Show More
policies that will affect the future of this planet. Alas, not so much so. I think this book needs an exhaustive revision so that the problems, consequences and solutions are presented with coherent flow, momentum, grip and clarity. So that the people who are not already convinced about the seriousness of the situation can be engaged. It is already a bad thing that most of the public reading this kind of literature are the ones that do not need to be convinced. And finally, since this subject is so important I will nevertheless recommend this book and advice some lenience.

Professor Wilson's optimism seems a little over the top, but OK, I'm in.
