Now, my polar bear experience has been presented in my town during the ice exhibition. You can see the figure at night and the animal frozen until the equilibrium is broken because warm temperature.
As of 2008, the World Conservation Union (IUCN) reports that the global population of polar bears is 20,000 to 25,000, and is declining. In 2006, the IUCN upgraded the polar bear from a species of least concern to a vulnerable species. It cited a “suspected population reduction of >30% within three generations (45 years)”, due primarily to climate change. Other risks to the polar bear include pollution in the form of toxic contaminants, conflicts with shipping, stresses from recreational polar-bear watching, and oil and gas exploration and development. The IUCN also cited a “potential risk of over-harvest” through legal and illegal hunting.
According to the World Wildlife Fund, the polar bear is important as an indicator of arctic ecosystem health. Polar bears are studied to gain understanding of what is happening throughout the Arctic, because at-risk polar bears are often a sign of something wrong with the arctic marine ecosystem.
