Are polar bears increasing or decreasing?

A projection of sea ice in the archipelago, supported by WWF, shows that much of the region is facing significant ice loss in the coming decades – with potentially serious consequences for polar bears. Global polar bear numbers are projected to decline by 30% by 2050.

What are 3 reasons why polar bears are endangered?
