Scientists check for effects of ag runoff; can a CSA ever be too big?

On this week's show, we'll discuss ag runoff and community supported agriculture.

Midwest waterways are getting lots of attention this summer. Scientists from the U.S. Geological Survey and the Environmental Protection Agency have immersed themselves in the ecology of 100 streams from Ohio to Nebraska. It’s a first-of-its kind effort to understand how ag runoff is not just changing the water but affecting the critters that live there. Harvest Public Media’s Abbie Fentress Swanson joined a crew on a rainy day while they gathered water samples and searched for fish eggs on three streams in central Missouri.

Also, Community Supported Agriculture, or CSA’s, allow consumers to buy shares of eggs, meat, fruit and veggies from a farm at the beginning of the season. Most operations are small, serving dozens of customers. Others serve hundreds. But can a CSA ever become too big. Reporting for Harvest Public Media, Grace Hood shares the story of the rise and fall of one of the country’s largest CSA programs--an organic farm in Northern Colorado.
