In the 1800s, Illinois’ oak forests once accounted for 60 percent of the state’s tree population. Today, they comprise only 5 percent and are being supplanted by native maple trees and several invasive species.

Water experts worried about Asian carp may have new hope. They’re turning their eyes to China, where a carp-hungry populace may be the key for stemming the tide of the invasive fish.

Asian carp are taking over U.S. waterways, including the Mississippi River and tributaries like the Illinois and Missouri Rivers, where they out-compete native fish.

In China, carp is cheap and a common meal-time fixture. Now, a carp fishing industry is springing up along carp-infested U.S. waters and processors are exporting the U.S. problem fish to Chinese diners.
