In 40 years, Earth's population will reach 10 billion. Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups - Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin.

The story of the "Lentil Underground" begins on a 280-acre homestead rooted in America's Great Plains: the Oien family farm. Forty years ago, corporate agribusiness told small farmers like the Oiens to "get big or get out." But 27-year-old David Oien decided to take a stand, becoming the first in his conservative Montana county to plant a radically different crop: organic lentils. Unlike the chemically dependent grains American farmers had been told to grow, lentils make their own fertilizer and tolerate variable climates, so their farmers aren't beholden to industrial methods.

Jeffrey Sachs - celebrated economist, special advisor to the Secretary General of the United Nations, and author of the influential best seller The End of Poverty - disagrees. In his view, poverty is a problem that can be solved. With single-minded determination he has attempted to put into practice his theories about ending extreme poverty, to prove that the world's most destitute people can be lifted onto "the ladder of development."

Life is getting better at an accelerating rate. Food availability, income, and life span are up; disease, child mortality, and violence are down all across the globe. Though the world is far from perfect, necessities and luxuries alike are getting cheaper; population growth is slowing; Africa is following Asia out of poverty; the Internet, the mobile phone, and container shipping are enriching people's lives as never before.

In This Changes Everything Naomi Klein argues that climate change isn’t just another issue to be neatly filed between taxes and health care. It’s an alarm that calls us to fix an economic system that is already failing us in many ways. Klein meticulously builds the case for how massively reducing our greenhouse emissions is our best chance to simultaneously reduce gaping inequalities, re-imagine our broken democracies, and rebuild our gutted local economies.

If you had the resources to accomplish something great in the world, what would you do? Legendary investor Warren Buffett posed this challenge to his son in 2006, when he announced he was leaving the bulk of his fortune to philanthropy. So, Howard G. Buffett set out to help the most vulnerable people on Earth - nearly a billion individuals who lack basic food security. And Howard has given himself a deadline: 40 years to put more than $3 billion to work on this challenge.

In The End of Plenty, award-winning environmental journalist Joel K. Bourne Jr. puts our race to feed the world in dramatic perspective. With a skyrocketing world population and tightening global grain supplies spurring riots and revolutions, humanity must produce as much food in the next four decades as it has since the beginning of civilization to avoid a Malthusian catastrophe. Yet climate change could render half our farmland useless by century's end.

Twenty years ago, with The End of Nature, Bill McKibben offered one of the earliest warnings about global warming. Those warnings went mostly unheeded; now, he insists, we need to acknowledge that we've waited too long, and that massive change is not only unavoidable but already under way. Our old familiar globe is suddenly melting, drying, acidifying, flooding, and burning in ways that no human has ever seen.

Weisman visits an extraordinary range of the world's cultures, religions, nationalities, tribes, and political systems to learn what in their beliefs, histories, liturgies, or current circumstances might suggest that sometimes it's in their own best interest to limit their growth.

In 2002, the town of Galesburg, a slowly declining Rustbelt city of 33,000 in western Illinois, learned that it would soon lose its largest factory, a Maytag refrigerator plant that had anchored Galesburg's social and economic life for decades. Workers at the plant earned $15.14 an hour, had good insurance, and were assured a solid retirement. In 2004, the plant was relocated to Reynosa, Mexico, where workers sometimes spent 13-hour days assembling refrigerators for $1.10 an hour.

In the mid-1930s, North America's Great Plains faced one of the worst man-made environmental disasters in world history. Donald Worster's classic chronicle of the devastating years between 1929 and 1939 tells the story of the Dust Bowl in ecological as well as human terms. Twenty-five years after his book helped to define the new field of environmental history, Worster shares his more recent thoughts on the subject of the land and how humans interact with it.

Through fascinating and accessible interviews with celebrity chefs, ranchers, farmers, and top scientists, this remarkable book, soon to be a full-length documentary film narrated by Woody Harrelson, will teach you how to become an agent in humanity's single most important and time sensitive mission. Reverse climate change and effectively save the world - all through the choices you make in how and what to eat.

Let There Be Water illustrates how Israel can serve as a model for the United States and countries everywhere by showing how to blunt the worst of the coming water calamities. Even with 60 percent of its country made of desert, Israel has not only solved its water problem; it also has an abundance of water. Israel even supplies water to its neighbors - the Palestinians and the Kingdom of Jordan - every day.

How much do you know about the meat on your dinner plate? Journalist Christopher Leonard spent more than a decade covering the country's biggest meat companies, including four years as the national agribusiness reporter for the Associated Press. Now he delivers the first comprehensive look inside the industrial meat system, exposing how a handful of companies executed an audacious corporate takeover of the nation's meat supply.

Farm animals have been disappearing from our fields as the production of food has become a global industry. We no longer know for certain what is entering the food chain and what we are eating - as the UK horsemeat scandal demonstrated. We are reaching a tipping point as the farming revolution threatens our countryside, health, and the quality of our food wherever we live in the world.
