In Arkansas, there is a kind of David vs. Goliath battle underway over a weedkiller.

On one side, there is the giant Monsanto Company. On the other, a committee of 18 people, mostly farmers and small-business owners, that regulates the use of pesticides in the state. It has banned Monsanto's latest way of killing weeds during the growing season.

Terry Fuller is on that committee. He never intended to pick a fight with a billion-dollar company. "I didn't feel like I was leading the charge," he says. "I felt like I was just trying to do my duty."

The Trump administration is proposing a major shake-up in one of the country's most important "safety net" programs, the Supplemental Nutrition Assistance Program, formerly known as food stamps. Under the proposal, most SNAP recipients would lose much of their ability to choose the food they buy with their SNAP benefits.

The proposal is included in the Trump administration budget request for fiscal year 2019. It would require approval from Congress.

Honeybees are amazing and adorable, and they suffer when people spray pesticides or mow down wildflowers. We've heard plenty in recent years about collapsing bee colonies.

So Jonas Geldmann, at the University of Cambridge, says he understands how the honeybee became a symbol of environmental conservation.

But he still doesn't like it.

"Lots of conservation organizations are promoting local honey, and even promoting sponsorships of honeybees and that kind of stuff, and that increasingly annoyed me," he says.

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.

This year, trucks and other heavy-duty motors in America will burn some 3 billion gallons of diesel fuel that's made primarily from vegetable oil. They're doing it, though, not because it's cheaper or better, but because they're required to, by law.

The law is the Renewable Fuel Standard, or RFS. For some, especially Midwestern farmers, it's the key to creating clean energy from American soil and sun. For others — like many economists — it's a wasteful misuse of resources.

The federal government's top fisheries experts say that three widely used pesticides — including the controversial insecticide chlorpyrifos — are jeopardizing the survival of many species of salmon, as well as orcas that feed on those salmon.

It's a fresh attack on a chemical that the Environmental Protection Agency was ready to take off the market a year ago — until the Trump administration changed course.

For at least the past decade, the Grocery Manufacturers Association (GMA) has been the unrivaled voice of a vast industry, from neighborhood grocery stores to food manufacturing giants with supply chains that span the globe. Most recently, it's been a powerful force in fighting proposals to require information about added sugar or GMOs on food labels.

Wintertime is a special time of year at Cafe Berlin, located just a few blocks from the Capitol building in Washington, D.C.

This is when they roll out their menu of wild game, such as deer, wild boar, and quail. Regular customers have come to expect it. "They ask, weeks in advance, 'When does the wild game menu start? When does it start?' " says James Watson, one of the restaurant's chefs.

Allie Hill got really serious about eating local food about eight years ago. She was cooking for three young children. "I was able to go to the farmers' market and find my produce — fruits and veggies," she says. "I was able to find meat, and even some dairy."

She simply couldn't find local version of other foods, though. These are foods that fill her pantry, like marinara sauce, apple sauce and everything else that comes to us preserved in sealed jars and cans.

The Trump administration has announced plans to withdraw a regulation that would have required organic egg producers to give their hens room to graze outdoors.

Something unprecedented happened this week. The Food And Drug Administration released its annual accounting of antibiotics sold in America for use in poultry, pigs and cattle, and for the very first time, it reported that fewer of the drugs were sold. Sales of medically important antibiotics in 2016 declined by 14 percent, compared to 2015.

Telling people what to eat is perilous, whether the advice is aimed at a friend or an entire country. Of course, people and governments do it anyway. Dozens of countries have come up with recommendations for the perfect, most health-promoting diet.

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.)

The gap between rich and poor is one of the great concerns of modern times. It's even driving archaeologists to look more closely at wealth disparities in ancient societies.

"That's what's so fun about it," says Timothy Kohler, at Washington State University. "It widens our perspective, and allows us to see that the way things are organized now is not the only way for things to be organized."

The World Health Organization, worried about an increasing epidemic of drug-resistant infections, has thrown its considerable weight behind the campaign to cut the use of antibiotics in pigs, chickens and cattle that are raised for their meat. The WHO is calling on governments to follow the example of Denmark and the Netherlands, which have banned the use of these drugs to make animals grow faster, or simply to protect healthy animals from getting sick.

Dave Chapman and dozens of other longtime organic farmers packed a meeting of the National Organic Standards Board in Jacksonville, Fla., this week. It was their last-ditch effort to strip the organic label from a tide of fluid-fed, "hydroponic" greenhouse-grown vegetables that they think represent a betrayal of true organic principles.

In a normal year, Kevin Bradley, a professor of weed science at the University of Missouri, would have spent his summer testing new ways to control a troublesome little plant called water hemp.

This has not been a normal year.

The Environmental Protection Agency announced Friday that it will let farmers keep spraying the weedkilling chemical dicamba on Monsanto's new dicamba-tolerant soybeans and cotton. The decision is a victory for the biotech giant and the farmers who want to use the company's newest weedkilling technology.

There is one small field on Michael Sullivan's farm, near the town of Burdette, Ark., that he wishes he could hide from public view.

The field is a disaster. There are soybeans in there, but you could easily overlook them. The field has been overrun by monsters: ferocious-looking plants called pigweeds, as tall as people and bursting with seeds that will come back to haunt any crops that Sullivan tries to grow here for years to come.

"I'm embarrassed to say that we farm that field," Sullivan says. "We sprayed it numerous times, and it didn't kill it."

Manuel Perez is a veterinarian who specializes in caring for cattle, and he knows many of Puerto Rico's dairy farmers.

Yesterday, he got in his truck and went to visit one of them, Jose Antonio Lopez. The route he took, along the island's northern coast, winds past forests. Until a week ago, when Hurricane Maria ripped through, it was beautiful.

"I tell you, it's just gone. It's all gone," Perez says. "A lot of the trees are down, and the trees that are standing don't have any leaves at all."

Arkansas is on the verge of banning the use, during the growing season, of a Monsanto-backed weedkiller that has been blamed for damaging millions of acres of crops in neighboring farms this year.

The weedkiller is called dicamba. It can be sprayed on soybeans and cotton that have been genetically modified to tolerate it. But not all farmers plant those new seeds. And across the Midwest, farmers that don't use the herbicide are blaming their dicamba-spraying neighbors for widespread damage to their crops — and increasingly, to wild vegetation.

The organic eggs in your grocery store are supposed to come from chickens that have year-round access to the outdoors. That's according to long-standing organic regulations.

When the worst of Irma's fury had passed, Gene McAvoy hit the road to inspect citrus groves and vegetable fields. McAvoy is a specialist on vegetable farming at the University of Florida's extension office in the town of LaBelle, in the middle of one of the country's biggest concentrations of vegetable and citrus farms.

It took a direct hit from the storm. "The eyewall came right over our main production area," McAvoy says.

If you are the kind of person who picks up a box of food in the store and studies the label to see how much sugar or salt is in it, you can thank a man named Michael Jacobson.

Earlier this week, as torrents of rain fell on Houston, Craig Boyan, CEO of the H-E-B supermarket chain, went on a video-taped tour of his company's emergency operations center in San Antonio, Texas. The company later made the video available online.

Brent Deppe is taking me on a tour of the farm supply business, called Key Cooperative, that he helps to manage in Grinnell, Iowa. We step though the back door of one warehouse, and our view of the sky is blocked by a gigantic round storage tank, painted white.

"This is the liquid nitrogen tank," Deppe explains. "It's a million-and-a-half gallon tank."

Nitrogen is the essential ingredient for growing corn and most other crops. Farmers around here spread it on their fields by the truckload.

The Environmental Defense Fund opened an office near Walmart's headquarters in Bentonville, Ark., 10 years ago. It was part of a carefully plotted strategy to persuade the giant retailer that going green could be good for business. If it worked, it certainly could be good for the planet — Walmart's revenues are bigger than the entire economy of most countries.

"We really saw that working with companies could be transformative at a scale that was pretty unmatched," says Suzy Friedman, a senior director at EDF.

Wild bees, such as bumblebees, don't get as much love as honeybees, but they should. They play just as crucial a role in pollinating many fruits, vegetables and wildflowers, and compared to managed colonies of honeybees, they're in much greater jeopardy.

It has become a rite of summer. Every year, a "dead zone" appears in the Gulf of Mexico. It's an area where water doesn't have enough oxygen for fish to survive. And every year, the National Oceanic and Atmospheric Administration commissions scientists to venture out into the Gulf to measure it.

In a vast, dimly lit barn near Frankford, Delaware, surrounded by tens of thousands of young chickens, about a dozen people in ghostly white coveralls are considering future options for the poultry industry.
