Climate Change Update: Polar Bear Cubs Drowning Due To Climate Change | Planetsave

Polar Bear Cubs Drowning Due To Climate Change | Planetsave: "A group of biologists that have been studying polar bears off the coast of Alaska have determined that polar bear cubs are drowning, due to loss of sea ice. They are being forced to make longer swims than normal just to find land or stable ice sheets.

Of the bears that were tracked, eleven bears that swam long distances had young cubs at the time of the collar deployment. Five of those bears lost their cubs while swimming, a 45 percent mortality rate. Among cubs not compelled to swim long distances, the mortality rate was 18 percent."
