The Faroe Islands, a windswept group in the North Atlantic, have no native land mammals apart from those introduced by people. Sheep have grazed the steep green slopes for over a thousand years and now outnumber the human population. Because the islands lie in the path of mild ocean currents, winters are surprisingly gentle for such a northern latitude, though fog and rain are frequent. Roads connect many islands through undersea tunnels, and one tunnel even contains a roundabout beneath the sea. Tourism has grown steadily, yet the local government carefully limits visitor numbers at the most fragile natural sites.
