The Day of the Polar Bear

It always falls on February 27th every year.

People are being called on all over the world to take steps to reduce carbon production this day. It's nothing complicated, just a day less or better than ever to drive a car.

Polar bears are at risk due to climate change. They need sea ice when they're on seals.

Bears are dependent on sea ice and the availability of their prey. They do not have their territory because their sea ice station is still moving and changing seasonally (it widening in winter and narrowing in summer). The government and scientists identified 19 populations of bears located in 4 different Arctic sea areas. They are spread over 5 countries (Canada, United States - Alaska, Greenland, Russia and Norway).

The polar bear is adapted to body temperature by low temperature, snow and ice, and swimming in ice water. They keep themselves at the edges of sea ice and feed the seals. The bear's fatty tissue is 10 cm thick and protects against freezing temperatures. Temperatures above + 10 ° C tolerate poorly and get into a state of hyperthermia (overheating of the body). They live in the wild for 25 years. The polar bear is classified as a vulnerable species.

Bears originally pursued and hunted natives for their skin, fat, and meat. Later they were hunted for commercial use of their body parts, but they were often only trophy hunts. Since 1973, hunting has been limited.

At a distance of about a few kilometers, the black muzzle of a bear can be seen on a clear day by the telescope. The bear is difficult to capture thermowitz because its fur is a great insulator. It can develop speeds up to 40 km per hour. It usually runs at a speed of 3 km to 6.5 km per hour.

The seals live. Waiting for the clock on the edge of the cry and waiting for the prey. During the day they travel tens of kilometers for food. They climb on perpendicular rats and skip up to 4 m holes in ice. They can dive and underwater they can stay for up to 3 minutes. By swimming, they can get up to hundreds of miles away and keep up to 10 days to swim. With his bite, he crushes his head or pulls it under the surface and kills. They can also catch walruses and sometimes small cetaceans. In summer they feed on berries and small terrestrial mammals or oars.

In 1774, the English Royal Navy officer, John Phipps, first described and assigned the scientific name Ursusmaritimus (marine bear) based on his life. The bear is a marine mammal, although it is dependent on ice cubes.

The aim of this day is to raise awareness of the impact of global warming and the reduction of sea ice on the polar bear population.
