Dan Charles

Dan Charles is NPR's food and agriculture correspondent.

Primarily responsible for covering farming and the food industry, Charles focuses on the stories of culture, business, and the science behind what arrives on your dinner plate.

This is his second time working for NPR; from 1993 to 1999, Charles was a technology correspondent at NPR. He returned in 2011.

During his time away from NPR, Charles was an independent writer and radio producer and occasionally filled in at NPR on the Science and National desks, and at Weekend Edition. Over the course of his career Charles has reported on software engineers in India, fertilizer use in China, dengue fever in Peru, alternative medicine in Germany, and efforts to turn around a troubled school in Washington, DC.

In 2009-2010, he taught journalism in Ukraine through the Fulbright program. He has been guest researcher at the Institute for Peace Research and Security Policy at the University of Hamburg, Germany, and a Knight Science Journalism fellow at the Massachusetts Institute of Technology.

From 1990 to 1993, Charles was a U.S. correspondent for New Scientist, a major British science magazine.

The author of two books, Charles wrote Master Mind: The Rise and Fall of Fritz Haber, The Nobel Laureate Who Launched the Age of Chemical Warfare (Ecco, 2005) and Lords of the Harvest: Biotech, Big Money, and the Future of Food (Perseus, 2001) about the making of genetically engineered crops.

Charles graduated magna cum laude from American University with a degree in economics and international affairs. After graduation Charles spent a year studying in Bonn, which was then part of West Germany, through the German Academic Exchange Service.

At the Center for Tropical Agricultural Research and Education (CATIE) in Turrialba, Costa Rica, you can touch the history of coffee — and also, if the optimists have their way, part of its future.

Here, spread across 25 acres, are coffee trees that take you back to coffee's origins.

"The story starts in Africa, no? East Africa," says Eduardo Somarriba, a researcher at CATIE, as we walk through long rows of small coffee trees.

What does it take to find guilt-free coffee?

Much of our coffee comes from places where the environment is endangered and workers earn very little — sometimes, just a few dollars for a whole day's work. Coffee farmers have helped cut down tropical forests, and most of them use pesticides.

Coffee is more than a drink. For many of us — OK, for me — it's woven into the fabric of every day.

It also connects us to far corners of the globe.

For instance, every Friday, a truck pulls up to the warehouse of Counter Culture Coffee, a small roaster and coffee distributor in Durham, N.C., and unloads a bunch of heavy burlap sacks.

My first reaction when I heard details of this week's deadly fertilizer explosion in Texas was horror.

My second thought was, "Maybe I shouldn't have pushed to change that headline."

The White House unveiled its proposal Wednesday for drastic changes in government programs that donate food to fight hunger abroad — and surprised no one.

As we reported last week, rumors of such an overhaul had been circulating for weeks, arousing both hope and anger among organizations involved in global anti-hunger programs.

Washington is awash in rumors this week that the White House is planning major changes in the way the U.S. donates food to fight hunger in some of the world's poorest countries.

It has set off an emotional debate. Both sides say they are trying to save lives.

America's policies on food aid are singularly generous — and also unusually selfish. On the generous side, the U.S. spends roughly $1.5 billion every year to send food abroad, far more than any other country.

Environmentalists and beekeepers are calling on the government to ban some of the country's most widely used insect-killing chemicals.

The pesticides, called neonicotinoids, became popular among farmers during the 1990s. They're used to coat the seeds of many agricultural crops, including the biggest crop of all: corn. Neonics, as they're called, protect those crops from insect pests.
