A new study found by the University of Washington a trend toward earlier sea ice melt in the spring and later ice growth in the fall across all 19 polar bear populations. This can negatively impact the feeding and breeding capabilities of the bears. Polar bears are among the animals most affected by the seasonal and year-to-year changes in Arctic sea ice. Because they rely on this surface for essential activities such as hunting, traveling and breeding. Nineteen separate polar bear populations live throughout the Arctic, spending their winters and springs on sea ice and hunting. Date: September 14, 2016 Source: University of Washington The Polar bears are one of the hundreds of species in endangerment of extinction. I think Polar bears need to be protected better. The shorter sea ice season is really affecting the bear’s diet. The Polar bears have evolved mainly to eat seals, which provide necessary fats and nutrients in the harsh Arctic environment. Polar bears can't outswim their prey, so they perch on the ice and ambush seals at breathing holes or break through the ice to access their dens. They are capable of existing on land for part of the year, but the sea ice is where they obtain their main food source. This is why it is so important to keep a healthy environment for the Polar bears. I LOVE POLAR BEARS:)
