River ecosystems have withstood drought, floods, wildfires and more. Human impacts, however, are unprecedented.
Ecologist Carter Johnson says its impossible to overstate the influence we've had on our rivers. He joined In the Moment to talk about South Dakota's rivers, streams and brooks.
Plus, we'll meet nature's top river-based engineer.
Johnson is co-author of the book "Ecology of Dakota Landscapes" and professor emeritus at South Dakota State University.
