Daniel 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.

Millions of newly impoverished people are turning to the charitable organizations known as food banks. Mile-long lines of cars, waiting for bags of free food, have become one of the most striking images of the current economic crisis. Donations are up, too, including from a new billion-dollar government effort called the Farmers to Families Food Box Program.

Tyson Foods, one of the biggest meat producers in the U.S., is suspending work at its pork processing plant in Waterloo, Iowa. Officials in Black Hawk County, where the plant is located, say at least 150 people with close connections to the plant have tested positive for the coronavirus, according to Iowa Public Radio.

Paul TenHaken, the 42-year-old mayor of Sioux Falls, South Dakota, said it wasn't easy getting the world's top pork producer to shut down one of its biggest plants.

"It was tense," TenHaken said. "You know, you shut down a plant like that, it has a pretty big impact on the food supply. So we weren't taking this lightly, making this request."

Several meat processing plants around the U.S. are sitting idle this week because workers have been infected with the coronavirus. Tyson Foods, one of the country's biggest meat processors, says it suspended operations at its pork plant in Columbus Junction, Iowa, after more than two dozen workers got sick with COVID-19. National Beef Packing stopped slaughtering cattle at another Iowa plant, and JBS USA shut down work at a beef plant in Pennsylvania.

Scientists are currently carrying out a trial to see whether a drug that's currently used to treat lupus and to prevent malaria might also help treat COVID-19.

Their interest is based on laboratory studies showing that the drug, hydroxychloroquine, blocked the coronavirus from entering cells. There's no solid evidence, as yet though, that the drug actually is an effective COVID-19 treatment.

In fact, medical experts have warned against buying it for that purpose, because that might exhaust supplies for people who actually need it.

In recent days, top U.S. government officials have moved to assure Americans that they won't lack for food, despite the coronavirus.

As he toured a Walmart distribution center, Vice President Pence announced that "America's food supply is strong." The Food and Drug Administration's deputy commissioner for food, Frank Yiannas (a former Walmart executive) told reporters during a teleconference that "there are no widespread or nationwide shortages of food, despite local reports of outages."

Vice President Mike Pence said the White House may ask hospitals to use some of their federal aid to cover the medical costs of COVID-19 treatment for people who have lost their health insurance in recent weeks, along with their jobs.

Some medical experts have called on the administration to allow newly uninsured people to sign up for health insurance under Obamacare. But at a White House briefing on Thursday, President Trump rejected that idea, saying that "we're doing better than that" with what he called "a cash payment."

At a White House briefing on Tuesday, Dr. Deborah Birx, the coronavirus response coordinator, laid out a grim vision of the future.

The best computer models, she said, predict that between 100,000 and 200,000 Americans will die from COVID-19 during the coming months, even if the country continues the strict social distancing measures that most states have adopted. Relaxing those restrictions would send the toll much higher.

Thousands of farmworkers are now carrying a new document with them on the road, in case they get stopped. Barbara Resendiz got hers last Friday, together with her paycheck. The small card explains that the Department of Homeland Security considers her job to be part of the nation's critical infrastructure and that she needs to get to work, despite California's order to shelter in place.

As Americans scattered to the privacy of their homes this week to avoid spreading the coronavirus, the opposite scene was playing out in the Mexican city of Monterrey.

A thousand or more young men arrived in the city, as they do most weeks of the year, filling up the cheap hotels, standing in long lines at the U.S. Consulate to pick up special H-2A visas for temporary agricultural workers, then gathering in a big park to board buses bound for farms in the United States.

In northeastern Kansas, there's an open-air ecological laboratory called Konza Prairie. Scientists like Ellen Welti go there to study plants, insects, and big animals. "In the spring it has a lot of beautiful flowers, it has bison; everybody should go visit and check it out for themselves," says Welti, who is currently a post-doctoral researcher at the University of Oklahoma.

In this landscape, grasshoppers play a crucial role. They eat the grass; birds eat them.

There's new evidence that a widely used family of pesticides called neonicotinoids, already controversial because they can be harmful to pollinators, could be risky for insects and fish that live in water, too.

The evidence comes from Lake Shinji, which lies near Japan's coast, next to the Sea of Japan.

Masumi Yamamuro, a scientist with the Geological Survey of Japan, says the lake is famous for its views of the setting sun. "It's amazingly beautiful," she says.

John Draper and I are sitting in the cab of a tractor on the research farm he manages for the University of Maryland, alongside the Chesapeake Bay. Behind us, there's a sprayer.

"So, away we go!" Draper says. He pushes a button, and we start to move. A fine mist emerges from nozzles on the arms of the sprayer.

We're spraying glyphosate, killing off this field's soil-saving "cover crop" of rye before planting soybeans.

Farmers have been using this chemical, often under the trade name Roundup, for about four decades now.

The company Calyxt, just outside St. Paul, Minn., wanted to make a new kind of soybean, with oil that's a little healthier — more like olive oil.

As it happens, some wild relatives of soybeans already produce seeds with such "high oleic" oil — high in monounsaturated fat. It's because a few of their genes have particular mutations, making them slightly different from the typical soybeans that farmers grow.

There was a moment, about 20 years ago, when farmers thought that they'd finally defeated weeds forever.

Biotech companies had given them a new weapon: genetically engineered crops that could tolerate doses of the herbicide glyphosate, also known by its trade name, Roundup. Farmers could spray this chemical right over their crops, eliminate the weeds, and the crops were fine.

When NPR interviewed Rep. Alexandria Ocasio-Cortez in February about her Green New Deal, she said that her goal was bigger than just passing some new laws. "What I hope we're able to do is rediscover the power of public imagination," she said.

Well, we're unleashing our imagination and exploring a dream, a possible future in which we're bringing global warming to a halt. It's a world in which greenhouse emissions have ended.

Twenty five years ago, William Happer had an encounter with the White House that ended badly.

This week, the governor of Connecticut proposed a statewide tax on sugar-sweetened drinks. Several cities have already enacted such soda taxes to raise money and fight obesity. And there's new evidence suggesting that these taxes do work — although sometimes not as well as hoped.

Jane Polston and I are walking over to some greenhouses at the University of Florida, where she's a professor. She wants to show me how viruses infect plants, which has been the focus of her professional life ever since she first learned about plant viruses, back in college.

"I just fell in love," she says.

"With viruses?" I ask.

"Yeah. Isn't that weird? That's what scientists do. They say, 'Oh, my God, I'm in love with this!' "

After years of insisting that it wasn't economically feasible, the world's biggest hog producer has bowed to public pressure and agreed to change the way it handles manure on more than 1,000 farms it controls in the U.S.

Smithfield Foods is promising to cover the manure ponds with a layer of plastic.

The fields and back roads of eastern Arkansas were a crime scene this past summer. State inspectors stopped alongside fields to pick up dying weeds. They tested the liquids in farmers' pesticide sprayers. In many cases, they found evidence that farmers were using a banned pesticide. Dozens of farmers could face thousands of dollars in fines.

The illnesses started appearing in late March. Here and there, across the country, people were checking themselves in to hospitals, sick from toxic E. coli bacteria. At least 200 people got sick. Five of them died.

A tablespoon of soil contains billions of microscopic organisms. Life on Earth, especially the growing of food, depends on these microbes, but scientists don't even have names for most of them, much less a description.

That's changing, slowly, thanks to researchers like Noah Fierer, at the University of Colorado, Boulder. Fierer think microbes have lived in obscurity for too long. "They do a lot of important things for us, directly or indirectly, and I hope they get the respect they deserve," he says.

For more than a century, corn has been the most widely planted crop in the country and a symbol of small-town America. Think of the musical Oklahoma, where the corn is as tall as an elephant's eye, or the film Field of Dreams, in which old-time baseball players silently emerge from a field of corn.

Even farmers are partial to corn, says Brent Gloy, who grows some himself, on a farm in Nebraska. (He also graduated from the University of Nebraska. You know, the Cornhuskers.)

Dan Fazio says his phone is "ringing off the hook" these days.

He's executive director of WAFLA, an organization that helps fruit growers in Washington state find workers — and specifically, foreign workers who are allowed to enter the U.S. specifically as seasonal workers on farms.

The dream of reviving Puerto Rico's chocolate tradition took root in Juan Carlos Vizcarrondo's mind years ago.

He's always been obsessed with flowers and trees. As a boy, he planted so much greenery in his mother's backyard, there was hardly room to walk.

But in his thirties, he started planting cocoa trees, with their colorful pods full of magical seeds. "Something told me, just keep planting, because nobody has it! It's so strange, nobody has it!," he recalls.
