The new commemorative stamp issued on March 18th is dedicated to the protection of polar areas and glaciers and mark the International Polar Year 2007-2009. Brazilian Post chose two specimens (one native from Arctic and other from Antarctic) as symbols of endangered animals caused by recent climatic changes. The Leopard seal (Hydrurga leptonyx) is most common in the polar and subpolar waters of the Southern Hemisphere, along the coast of Antarctica and on most sub-Antarctic islands. Some individuals can be found on the coasts of South Africa, southern Australia, Tasmania, New Zealand, and the Atlantic coast of South America. The polar bear (Ursus maritimus) is a bear native to the Arctic Ocean and its surrounding seas. For decades, the world's largest carnivore found on land suffered unrestricted hunting, what raised international concern for the future of the species. Nowadays, scientists list global warming as the most significant threat to the polar bear, primarily because the melting of its sea ice habitat reduces its ability to find sufficient food.
