The arctic fox eats lemmings, arctic hares and some birds and bird eggs. But its main source of food is the lemming and its population size fluctuates with the cycle of the lemming population. © Staffan Widstrand / WWF

WWF: The Arctic

The Arctic – from the tundra, to the mountains, and to the sea itself – covers eight countries. It supports magnificent wildlife, the economy, and many cultures. Within the United States, the remarkable waters of the Arctic are home to whales, polar bears, walruses, and other wildlife found in few other places on Earth. The region is under threat from such factors as climate change, shipping, and oil and gas development. One of World Wildlife Fund’s top priorities in the region is protecting sensitive habitats and the people and wildlife that depend on them from these impacts. We bring together local communities, industries, governments, scientific institutions, and other conservation organizations to conserve this vibrant region.
