Loons, mergansers, cormorants and other waterfowl are dying by the thousands in the Great Lakes due to an invasion of non-native species that are threatening to turn the lakes' ecosystem upside down. At Sleeping Bear Sand Dunes National Lakeshore even piping plovers, a threatened species, are dying.
