Around the world, from US coastal towns to island nations of the Pacific and the deserts of Africa, people are in danger of losing their homes. Some have already fled. Others know they are running out of time. By 2050, at least 25 million people will be driven from their homes due to the effects of climate change.Droughts, desertification, rising sea levels, melting permafrost, and severe storms are drastically redefining the planet's landscape and leaving many places unable to support human populations. Although developing nations are especially vulnerable to the impacts of extreme climate shifts, ultimately, people in wealthy countries will also be forced to migrate. Experts expect Americans to move from drought-ravaged California, sea-swept Florida, and numerous other vulnerable areas to crowd into the few remaining safe havens.Humans cannot stop climate change altogether. Yet leaders can minimize the damage by curbing carbon dioxide emissions that contribute to climate change and by adapting communities to better withstand climate-related stresses. Even so, for many people, relocation is already a reality. How they adjust to their new homes—and how their new communities adjust to them—will set the stage for a future defined by a warming planet.

Whether you call them kicks or sneakers, runners or gutties, you probably have a pair of athletic shoes in your closet. The earliest sneakers debuted in the 1800s and weren't much more than a canvas upper and a flexible sole made of a crazy new material―rubber. The stuff might have been new to Americans then, but for thousands of years, the indigenous peoples of the Amazon Basin of South America had been using latex made from the milky sap of hevea trees to protect their feet from rocks, sticks, and biting insects. Once Charles Goodyear figured out how to make the stuff more durable, sneakers were here to stay. Early sneakers were initially designed for elite athletes, but kids and teens quickly adopted them. Some of the first brands included Converse, Brooks, and Saucony. German companies Adidas and Puma started up during World War II. The Nike shoe debuted in the 1970s (with a bit of inspiration from a waffle iron). As fitness crazes took off in the 1980s, people all over the world started buying the shoes for workouts and everyday wear. At about the same time, companies began hiring high-profile athletes and pop stars for big-dollar endorsements, and shoe sales soared into the stratosphere to the tune of billions of dollars each year. In Sneaker Century, follow sneaker fashions and the larger-than-life personalities behind the best known athletic shoe brands in history.

Trillions and trillions of microbial cells live on and inside your body. A small number of these microbes are unhealthy germs. But most belong on your body and perform essential jobs. Microbes help digest your food, protect you from dangerous germs, and help your body fight disease. Using techniques such as DNA sequencing, scientists are uncovering the many secrets of the human microbiome. Scientists are learning how the foods we eat and the medicines we take, such as microbe-killing antibiotics, can affect the bugs in our bodies. They are learning more and more about this system that keeps us healthy and how we can protect it in return.

"Trafficking thrives in the shadows. And it can be easy to dismiss it as something that happens to someone else, somewhere else. But that is not the case. Trafficking is a crime that involves every nation on earth, and that includes our own."—US secretary of state Hillary Rodham Clinton, 2009 Human trafficking is as old as slavery and continues to be practiced in the modern world. Victims of human traffickers include workers in restaurants and in garment factories, maids and nannies in the homes of wealthy families, child sex workers, beggars on the street, boy soldiers, even infants kidnapped for foreign adoptions. Women and children are more likely to be coerced or seized than men and boys, especially if they are poor and uneducated. Traffickers sell their victims for their bodies or for their labor and reap an enormous profit. Human trafficking is estimated to be a $30 to $45 billion industry on an annual basis, rivaling weapons and drug trafficking as one of the most profitable criminal undertakings in the world.Up for Sale takes a hard look at human trafficking, identifying perpetrators and telling the stories of victims through their own words.
