Can polar bears drown?
The result is that bears must swim further and further out to sea in search of ice floes; some expend all of their energy in doing so and end up drowning. Scientists first noticed this deadly phenomenon in 2004 when they noticed four drowned polar bears in the Beaufort Sea off Alaska’s North Slope.
Can polar bears swim in water?

Are polar bears dying?
Polar bears are listed as vulnerable to extinction by the International Union for Conservation of Nature (IUCN), with climate change a key factor in their decline. Studies show that declining sea ice is likely to decrease polar bear numbers, perhaps substantially.
Are polar bears going extinct 2020?
The Arctic where polar bears live is huge — about twice the size of the continental United States. The global number of polar bears stands between 22,000 and 31,000, or a midpoint of 26,500. The simple fact is that polar bears are not going extinct. They are not becoming fewer and fewer.
