Chicago Plans $18 Billion Defense Against Invasive Asian Carp After Reports Of 'Dangerous' Attacks On Boaters

The city of Chicago is considering several plans to keep an invasive species of fish from overrunning the Great Lakes, including spending $18 billion to shore up Chicago's canal system. The measure comes on the heels of several reports of Asian carp, a fish that can grow to be more than a yard long, jumping out of the water and bludgeoning boaters along the Mississippi River Basin.
