What Makes Polar Bears White
Polar bears have a thick layer of fur that helps them survive in the cold Arctic environment. The fur is made up of two layers, an outer layer of long, transparent guard hairs and an inner layer of short, dense underfur. The guard hairs are hollow and reflect light, which gives the polar bear its white appearance. […]
Impact of Climate Change
Climate change is a major threat to the polar bear population, as it is causing the Arctic sea ice to shrink at an alarming rate. Polar bears rely on the sea ice to hunt and travel, and the loss of sea ice is making it difficult for them to find food. As the sea ice […]
Polar Bear Physiology
Polar bears are the largest species of bear, with adult males weighing between 775 and 1,200 pounds and measuring up to 10 feet in length. Adult females are smaller, weighing between 330 and 650 pounds and measuring up to 8 feet in length. Their large size and weight are an adaptation to their harsh Arctic […]
Adaptations for Hunting
Polar bears are apex predators that are known for their hunting capabilities. They have several adaptations that enable them to hunt effectively in their environment. Camouflage One of the most important adaptations of polar bears for hunting is their white fur, which provides excellent camouflage in the Arctic environment. The white fur allows them to […]
Polar Bears Could Starve to Extinction Due To Global Warming
“The fate of the polar bear should alarm everyone” because the Arctic is a good “barometer” of the planet’s health. Since the 1980s, the ice pack in Hudson bay has decreased by nearly 50 per cent in summer, according to the US National Snow and Ice Data Centre. If a bear is lucky enough to […]
Polar Bears Lose Up To 2Kg Per Day
We’ve all seen the pictures of starving polar bears, struggling to survive climate change. But as global temperatures continue to rise, experts say bears today are spending up to a month longer than their parents waiting for the ice to return after summer. Every year, starting in late June when the bay ice disappears, polar […]
Polar Bears & Sea Ice Loss
Polar bears depend on sea ice for most important aspects of their lives – including hunting, mating and resting. While polar bears are strong swimmers, capable of swimming for hours on end, they find swimming much more energy intensive than walking. As such, sea ice is crucial for polar bears to survive. However, temperatures in […]
Polar Bear Impacts
As the climate warms, polar bears are being forced to change their behaviour, and their phenology – the timing of seasonal biological events, such as denning and breeding – is shifting. For example, research shows that as polar bears lose access to their typical diet of seals, they are becoming increasingly reliant on other types […]
Canada’s Polar Bear Population Plummets
The polar bear population in Canada’s western Hudson Bay has dropped by 27% in just five years, a report has said. A government report estimates that 618 animals lived in the area last year, down from 842 in 2016. It says adult female bears and cubs are particularly affected and that climate change may be […]
Polar Bears Toward Extinction
Polar bears could become nearly extinct by the end of the century as a result of shrinking sea ice in the Arctic if global warming continues unabated. While fasting, bears move as little as possible to conserve energy. But sea-ice loss and population declines create new problems — having to expend more energy searching for […]
