Some of the risk factors that contribute to its registration on the Species At Risk Public Registry are hunting, reduction of availability of their prey, the reduction of their melting sea ice, and pollution, but mainly human actions.
Polar bears were hunted more commonly in the past, since they have been considered at risk, they have been given regulations and laws to ensure their species survives, thus taking precautions such as putting a limit to hunting and killing the bears, whether they bring a threat when entering a community or village. There are still procedures that the officials have to follow before killing the bear, such procedures could include relocating the bear far away from the community.
The increasing process of the melting of the sea ice, thus limiting their food supply and their habitat. Their decreasing land mass (the sea ice) is majorly caused by the climate change in the Arctic, the warming temperatures. Due to the melting of the sea ice, polar bears are given a smaller time window to catch as many seals and food as they can till the sea ice melts. This results in polar bears traveling from the sea and traveling more into communities to find food, creating a greater risk for human safety.
The increase in pollution in their habitat plays a major role in their risk factors as well. Pollution entering the polar bears habitat especially when it associated with the offshore development of hydrocarbon reserves and the increased ship traffic. Oil as being extremely toxic, an increase in human activities brings higher risk of disturbance to essential areas, ex: areas for rearing cubs and feeding in the spring. The pollution enters their food supplies and water they drink, entering their body and causes illness and health issues. Containments such as Organochlorines that end up in the tissues of the polar bears and seals, they are said to impair endocrine function and immune function, in addition to having other adverse health problems. This then creates shorter life span for the polar bear species.
The more that humans interact with the polar bears habitat and damage their own surroundings affect the polar bears natural way of life, more at risk they are. By just the way humans burn so much fuel affects the polar bears from miles away. The burning of fossil fuels is most of the cause to climate change, humans can affect them directly with weapons, entering their habitats, and polluting their surroundings, or they can also affect the polar bears indirectly with the burning of greenhouse gases, polluting the waters, and decreasing their habitat range.
Another risk factor is climate change, changing temperatures and changing their habitat, polar bears are being forced on to landmasses and entering into communities to obtain food for their survival. The polar bears are being seen more prominently in communities usually trying to find food, because of the drastic changes in their...
