Beaverland

Biologists and lovebirds Derek and Giorgia have a mission: to do something about the plague of beavers on Tierra del Fuego. In 1946, fifty beavers were introduced to the island off the tip of South America, in the hope they would lead to a fur trade. Without predators, the pesky creatures have thrived, and now evidence of their uninterrupted industriousness is everywhere — elaborate dams, and gnawed trees being plentiful. In fact, they are completely changing the ecosystem of this island, killing the plants that shelter the penguins from the wind, and turning the island into grasslands. The locals, including the penguin keeper, are not happy about it, and wish Derek and Giorgia all the best. The trouble is, the beavers are rather good at eluding capture, working under the cover of night and disappearing in the day.
