polar bear : a large creamy-white carnivorous bear (Ursus maritimus synonym Thalarctos maritimus) that inhabits arctic regions — Webster
Polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi). A boar (adult male) weighs around 350–700 kg (772–1,543 lb), while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means “maritime bear” and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals — Wikipedia

Some of that emotional turmoil must stem from confusion – why aren't adults doing more to stop climate change?

Life over the last half-century has been pretty good for populations of Svalbard barnacle geese. A hunting ban implemented in the 1950s in their overwintering area in Scotland has led to explosive population growth, from roughly 2800 birds in 1960 to more than 40,000 birds today.

The Trump administration recently announced a proposal that would gut the Endangered Species Act. The news follows in the wake of a report from the United Nations earlier this year that more than 1 million plants and animals around the world face extinction, some within decades, owing to human development, climate change and other threats. Mark Urban, director of UConn's Center of Biological Risk, and associate professor of ecology and evolutionary biology, explains what the change would mean […]
