Polar bears enter the special protection list

Polar bears will soon be included in the special protection list under Canada's Endangered Species Act.

There are more than 15,000 polar white bears living in Northern Canada, accounting for about 60% of global white bear populations.

These bears are divided into 13 different communities, depending on the geographical area in which they live. The results of the latest studies show that 4/13 of these communities are in danger or are at risk of extinction.

Peter Ewins, a senior official at the Toronto-based World Wildlife Fund (WWF), stressed that in fact, the biggest risk for polar bears is the area and time to freeze. the same decline, and the protection of the polar bear's habitat requires action on a large scale.

The number of polar bears is continuing to decline due to climate change. The results of an University of Alberta study indicate that if the Hudson Bay ice sheet melted a month early because the Earth warms, about 40-73% of the bears will not be able to give birth; If the ice melts early two months, this number will be about 55-100%.

The reason that polar bear bears cannot give birth if the ice melts early is because females can only conceive and give birth if they reach a weight of over 200kg, it cannot happen if their hunting time on the ice reaches less than eight January a year.

The number of white bears worldwide is currently around 20,000-25,000.
