Oh yes! They are endangered, I was reading in a magazine that because the ice melts, a lot of bears can swim to exhaustion and die because they find no ice to put their feet on. I have found this to be utterly sad... Swimming until death because we humans have affected the climate so much.
I love to see how big animals like whales, dolphins, bears, seals, can be such delicate swimmers.
Oh don't forget our Happy Hippo that can walk/cruise/swim under water too, yes animals are having a rough time with climate change!
Oh yes the hippo!! Totally worth the mention!
