The fauna of the Arctic is not prepared to address global warming, which disrupts the habits. Polar bears are the first victims. With the retreat of sea ice, their "mess" is likely to close down: right on the ice, in fact, bears feed on seals from November to May and store enough fat reserves to be able to stay on the mainland in the summer when food is scarce.
Due to the disappearance of this precious "pantry," polar bears are threatened with extinction. According to the Canadian Wildlife Service, the 12,000 individuals reviewed west of Hudson Bay are already showing signs of fragility. The malnourished women are too weak to give birth to children and feed them properly. The birth rate is falling and the bears have lost stunted on average 15% of their weight. If nothing is done, the disappearance of these animals is only a matter of time.
Le renne della tundra non se la passano granché meglio. Le mandrie sono vittime di una conseguenza indiretta del riscaldamento, ossia il ghiaccio. Il suolo che disgela a 0°C, infatti, si ricongela molto rapidamente al minimo abbassamento della temperatura. Ma il ghiaccio è più duro della neve e The reindeer are not strong enough to be able to break it with blows of his hoof to get food. The animals die and the herds become smaller gradually.
