What is making the polar bears of the arctic passages die. is it less ice i do not know !

Global warming plays a big part. It’s melting the ice, which is not only where they hibernate, but they float on pieces of ice as well and it’s how they capture their food. Also, since the ice is melting and the water levels are rising, and it’s getting warmer, their main food source—which are mainly ringed and bearded seals—have probably begun to seek a colder climate. Seals also tend to chill out on those floating ice pieces that I mentioned and without them it’s harder for Polar Bears to eat. Polar Bears are very highly dependent on the seal population and they burn something like 13,000 calories a day. I think the average weight is something 900 lbs. I hope that made sense. If not here’s a link to an article done by National Geographic about dying Polar Bears: https://www.google.com/amp/s/relay.nationalgeographic.com/proxy/distribution/public/amp/2018/02/polar-bears-starve-melting-sea-ice-global-warming-study-beaufort-sea-environment
