The coronavirus pandemic could delay the removal of a 72-foot long fishing vessel that has been grounded for weeks on a beach on North Carolina’s Outer Banks. The scallop harvesting boat is considered a safety hazard as curious people climb aboard its rusting hull. The Virginian-Pilot reported Saturday that removing the abandoned boat could cost more than $60,000. The boat’s owner is responsible for its removal. But the owner lives in Texas. Stay-at-home orders have limited travel between states. Visitors are also banned from coming to the Outer Banks. The ship ran aground during a storm on March 1 near Oregon Inlet.

Picture an American farmer. Chances are, the farmer you’re imagining is white – more than 9 out of 10 American farmers today are. But historically, African Americans played a huge role in agriculture. The nation’s economy was built largely on black farm labor: in bondage for hundreds of years, followed by a century of sharecropping and tenant farming.

In the early 1900s, African American families owned one-seventh of the nation’s farmland, 15 million acres. A hundred years later, black farmers own only one-quarter of the land they once held and now make up less than 1 percent of American farm families.

The federal government has admitted it was part of the problem. In 1997, a report by the U.S. Department of Agriculture said discrimination by the agency was a factor in the decline of black farms. A landmark class-action lawsuit on behalf of black farmers, Pigford v. Glickman, was settled in 1999, and the government paid out more than $2 billion as a result. But advocates for black farmers say problems persist.

On this episode of Reveal, reporter John Biewen of “Scene on Radio” tells the story of a black farmer who says the USDA treated him unfairly because of his race.
