Lack of food · Scientists suspect that the rising temperatures affect the small fish and other marine animals on which penguins feed. · The sea ice necessary to the survival of krill larvae is disappearing earlier and taking with it 80 percent of the krill population. Climate changes · The emperor penguins are starving to death because the warming air and water is drastically changing the environment to which they have adapted. · Two giant icebergs have broken off the Antarctic ice sheet and are blocking the way from their breeding colonies to their feeding areas. As a result they have to walk 30 miles further to get food.
The interior ice cap is thickest near the centre of the island, where the maximum depth is estimated to be about 3,353 metres (11,000 feet). Underneath the ice cover are the ancient rocks of the Greenland Shield, which is geologically related to the Canadian Shield. Drainage is afforded mainly by the so called ice fjords, in which glaciers from the ice caps pass through valleys to the sea, where they form thousands of icebergs each year. The climate is extremely cold, although the south experiences a short summer. The mammals of Greenland are more American than European and include muskox, wolves, lemmings, and reindeer. The varieties of seal and whale, and most of the species of fish and seabird, are also American rather than European. Circumpolar animals, such as polar bears, arctic foxes, polar hares, and stoats, are also found.
Newfoundland Geography Newfoundland and Labrador is located on the eastern edge of North America. Newfoundland and Labrador is home to Iceberg Alley, one of the best places in the world to view icebergs. Just off the coast, the meeting of the cool Labrador Current and the warm Gulf Stream creates an abundance of marine life that attracts thousands of whales, and provides rich nesting grounds for millions of seabirds. To put things in perspective, Newfoundland and Labrador is a little smaller than California, slightly bigger than Japan, and twice the size of the entire United Kingdom. Geography The island of Newfoundland covers 111,390 square kilometres
