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.
On the shores of Lake Michigan, the tiny town of Ludington, Mich., is home port to the last coal-fired ferry in the U.S. The SS Badger has been making trips across the lake to Manitowoc, Wis., during the good-weather months since 1953. And as it runs, the 411-foot ferry discharges coal ash slurry directly into the lake.
An Environmental Protection Agency permit allows the Badger to dump four tons of ash into the lake daily. But now, the agency has put the permit under review — and that means the Badger could stop sailing.
