Drowning Polar Bears became one of the symbols of climate change, so we decided to find out what really happens with these magnificent creatures and created this video to share with other interested in.
The key danger posed by global warming to Polar Bears is malnutrition or starvation due to habitat loss. Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall. Reduction in sea-ice cover also forces bears to swim longer distances, which further depletes their energy stores and occasionally leads to drowning. Thinner sea ice tends to deform more easily, which appears to make it more difficult for polar bears to access seals. Insufficient nourishment leads to lower reproductive rates in adult females and lower survival rates in cubs and juvenile bears, in addition to poorer body condition in bears of all ages.
Other risks to the polar bear include pollution in the form of toxic contaminants, conflicts with shipping, stresses from recreational polar-bear watching, oil and gas exploration and development, as well "potential risk of over-harvest" through legal and illegal hunting. In this video we decided not to use graphic images of trophy hunters from The Humane Society of the United States but still must inform you that about 500 Polar Bears are killed by American and Canadian hunters every year.
In this video we used footage from BBC documentaries "Blue Planet" and "Polar Bear" (Wildlife Special), as well CBC Doc Zone documentary "Battle For The Arctic". As audio we used Eric Polaire song "Polar Bear" in remix from Michel Cleis.
And as with our other videos please watch in High Quality.
