Road Salt: Researchers look at vegetables and juices for alternatives to salt

Salt-speckled sidewalks, driveways and highways are synonymous with winter in the Great Lakes region. But while road salt is highly effective at deicing surfaces, the safety that salt provides for humans places a heavy burden on freshwater ecosystems.

“We have an unhealthy addiction to road salt,” said Claire Oswald, a hydrologist and associate professor at Ryerson University in Toronto, Ontario.

Shipwreck Life: How fish and other aquatic species utilize Great Lakes shipwrecks

Both were northern map turtles, the most common species of turtle in the Kalamazoo River watershed, according to Otten who played a key role in the rescue and rehabilitation of more than 2,000 turtles in 2010 following the Kalamazoo River oil spill.
