Environmental Woes of Tierra del Fuego -- Invasive Species

A pair of beavers dines along the shore of a small Fuegian lake. Among the 19 invading mammal species, the beaver is still considered the worst. All that separates the beaver from invading the mainland of South America is the Strait of Magellan, across which watch the fearful eyes of Chile and Argentina in hopes that they won't succeed. A spread of the industrious rodents up the Andean range would spell equal disaster for river systems there.
