Alaska's Giant Bears

In Canada and Alaska, brown bears are acutely experiencing the effects of global warming, though the impact varies among different populations. Their ability to thrive hinges on the availability of wild salmon, which is crucial for building up fat reserves for the winter. While salmon numbers off the Pacific coast of Canada continue to dwindle annually, the vast Bristol Bay in western Alaska and Kodiak Island are witnessing a significant rise in salmon populations. The North Pacific waters now offer perfect conditions for salmon growth. This documentary tracks various bear groups over two years, showcasing their contrasting fortunes.
