Asian Carps

There are illegal immigrants on the loose in the Midwest. Originally hailing from Asia, they're about 3 ft. (90 cm) long and weigh up to 100 lb. (45 kg), and are known to resist capture. Once they establish residency, they can eat you out of house and home. They're called Asian carp, and they emigrated to the lower reaches of the Mississippi River in the 1970s. Now they're knocking on the door of the Great Lakes, threatening to destroy one of the most valuable aquatic regions in the U.S., unless the often fractious Great Lakes states manage to pull together and keep them out. The situation is so serious that the White House convened an "Asian carp summit" on Monday to work out a defense plan. "If the carp invade the Great Lakes, it will change them forever," says Jennifer Nalbone, director of invasive species and navigation for the NGO Great Lakes United.
