Bold Plan for Earth: The Case for Setting Aside Half the Planet

This guy knows his stuff and his ants!

In his latest book, Pulitzer Prize–winning scientist Edward O. Wilson argues for a bold step in conservation

Few people know more about biodiversity than Edward O. Wilson. The 86-year-old Harvard biologist and two-time Pulitzer Prize winner helped popularize the term in a groundbreaking 1988 report of the same name. So when he argues in his new book, Half-Earth: Our Planet’s Fight for Life ($26, Liveright), that species loss is a critical threat and that we need to turn fully half the planet’s land surface into biodiversity reserves, it’s more than an idle thought experiment.

“To let things continue at the present rate, we could easily be down to half the species left on earth,” Wilson told me from his home in Lexington, Massachusetts. “We could lose millions just in the next few decades.”

Like many scientists, Wilson believes that the planet is currently experiencing a “sixth extinction,” during which species are disappearing as much as 1,000 times faster than they did before humans were around. And we have yet to even encounter the vast majority of life-forms among us. We’ve named approximately two million species, but the best estimates are that another 6.7 million, give or take a million, have yet to be discovered.

Slowing the rate of extinction has long been a crusade for Wilson. More than ten years ago he calculated that, in order to stop or significantly slow species loss, 50 percent of the earth’s land must be protected. (Currently, only 15 percent is formally preserved.) “The only way we’re going to save the situation is by radical means,” he says.

His Half-Earth proposal is certainly that. Many of the world’s preeminent naturalists helped him compile a list of areas with high biodiversity—not just the rainforests of the Congo and the Amazon, but also little-known spots like the church forests of Ethiopia and the just-opening wildlands of Myanmar.

Safeguarding an additional 35 percent of the earth comes with logistical challenges: Would people in preservation areas be relocated, or would they be allowed to stay? Would governments agree to such protections? Oddly, Wilson skips over these issues and instead spends a portion of the book criticizing “new conservationists,” a small group of individuals who believe that smart economic development rather than high fences is the best strategy to preserve what’s left of the wild.

Wilson lambasts people like Peter Kareiva, current director of the UCLA Institute of the Environment and Sustainability, who has advocated higher living standards as a way to save nature. Fearing a loss of emphasis on the nonhuman, Wilson uses his book as a club in this internecine fight. “I do believe they are dangerous,” he says. “I had to come down pretty hard on them.”

Kareiva, for his part, admires the Half-Earth idea. “Wilson has been a crusader for biodiversity unlike any other scientist,” he says. But he thinks the antagonism is misplaced. “If you sat us in a room and put a map in front of us and asked us what do we want the world to look like in 2050, we might end up with very similar maps.”

Indeed, in the second to last chapter of Half-Earth, Wilson makes the case for smart and fast development. Human population, he believes, will peak at around 11 billion near the end of the current century. (It now stands at 7.3 billion.) Technology will help transform the global economy from extensive (requiring large amounts of money, people, and natural resources) to intensive (boosting both productivity and efficiency). And energy production will continue to become less connected to fossil fuels. In short, over the coming decades, humanity will achieve a smaller footprint and leave room for other species. It’s the kind of argument a new conservationist might make.

“We’re finally seeing conservation starting to get more on point,” says Michael Shellenberger, president of the Breakthrough Institute, which has rattled mainstream environmentalism in part by arguing that it needs to embrace “ecomodernist” development to fix the planet. Shellenberger has his own critique of Wilson: “He doesn’t address the dirty, bloody work of conservation on the ground.”

Nor did he intend to. Half-Earth is less detailed plan than aspirational goal. Wilson is leaving it up to us to figure out how to do it, and after looking at the technological and economic trends, he believes we will. “The reason is that we are thinking organisms trying to understand how the world works,” he writes. “We will come awake.”

Wherever Wilson presents this idea, he is wildly cheered. He considers that evidence of a generation prepared to make tough decisions. “Many young people see in this something worthwhile to dedicate themselves to,” says Wilson. “This book is saying we don’t have to yield. We don’t have to plant the white flag and start setting ourselves up for the 
destruction of the living world.”

Earth, Protected

Though the book doesn’t include a comprehensive map of proposed sanctuaries, Outside assembled an approximate guide to the best places in the biosphere, according to Wilson 
and other scientists. —Nicola Payne

Homeland Security

The redwood forests of California, the South’s longleaf pine savanna, and the Madrean pine oak woodlands of the mountainous Southwest are crucial North American ecosystems.

Under Siege

The Amazon River basin, the forests of the Congo basin, and the church forests of Ethiopia have faced unrelenting decimation by human hands in recent years.

Hot Spots

Wilson and others believe that certain countries possess such rich biodiversity that the majority of their land is worthy of study and protection. These include Bhutan, Cuba, the Dominican Republic, Haiti, Myanmar, Madagascar, New Guinea, and South Africa.

Dear Friend of Interfaith Power & Light — 2/27/16

=== ===

The 2016 election will be critical in determining how our country responds to the climate crisis and if we follow through on the commitments we made to the rest of the world in Paris. We hope that all people of faith will consider the climate and care for Creation when they vote.

That’s why we encouraged Faith in Public Life to include climate in the Faith Voter Reflection Guide. For the first time, this influential guide includes a section called “Global Warming: A Threat to Creation and our Children’s Future,” along with other issues that are relevant to the faith voter. Feel free to print it out and share it with your faith community.

As a nonpartisan nonprofit 501(c)(3) organization we do not endorse specific candidates, nor do our congregations. But that doesn’t mean we can’t encourage and support our congregants in doing their civic duty and voting with their values in mind.

Click below to download the guide and get other tips on how your congregation can support you and your community in voting your faith this year.

If we work together, this will be the year that people of faith will stand up and demand that candidates for office address the most urgent moral issue of our time: climate change.

Leadership from the United States in both reducing our own emissions and supporting vulnerable nations around the world is critical if the Paris Accord is to be a success. These elections, which occur less than one year after the breakthrough in Paris when 195 nations agreed to act on climate change, will be a moment of truth. They will send powerful message to the rest of the world about where the United States stands on the issue.

It is not acceptable that cities are being poisoned by air pollution, washed away, or economically failing due to the impacts of global warming. Now is the time to say enough is enough. We must protect Creation for our children and grandchildren, and we must elect candidates who understand the urgency of the issue.

Interfaith Power & Light is pleased to be working with Faith in Public Life and other partners, to ensure that climate is one of the key issues people of faith take into account when they vote.

Sign up now to get the guide with the link below.

As Pope Francis reminds us, the Earth is our common home, and the climate belongs to everyone. Climate change is the greatest threat humans have ever faced. It will only be solved if people everywhere in the world act together. Let’s lead the way. Please help us make a difference by voting for the Earth this year.

Thank you, Susan Stephenson
