The Arctic is changing rapidly. This land has always been an extreme corner (regarding weather, daily routines, terrain features, etc.), but nowadays even fires can be seen in the tundra.
Air warming and rising sea temperatures are wreaking havoc on the Antarctic lands - the amount of eternal ice is decreasing, coastal erosion is growing every year. Fires in Alaska were not uncommon. This can be explained by critical air temperatures and climate drainage. Locals are at risk of losing their homes and lifestyle. Global warming is also dangerous for wildlife inhabitants, especially for species that live directly on ice, namely, for polar (polar) bears.Global warming threatens the extinction of polar bears.
In 2008, polar bears were listed as threatened by the United States Endangered Species Act (ESA), in particular because of the projected impacts of climate change on their habitats. The latest U.S. Geological Survey (USGS) modeling showed the need to reduce greenhouse gas emissions in the atmosphere to prevent the extinction of polar bear populations.
Decisive action was taken on July 2, 2008, when the U.S. Fish and Wildlife Service released its draft polar bear conservation plan, calling for timely and decisive reductions in greenhouse gas emissions to combat climate change. Reducing environmental pollution is the only way to curb the threat of extinction of polar bears, and it is very important that the public heed the recommendations on a plan to stabilize the environmental situation.
Animal species, the existence of which depends on the availability of centuries-old ice, in particular polar bears, are in a particularly vulnerable position, since the US Geological Survey announced the complete disappearance of ice at the North Pole by 2050, and it will take quite a while before it reappears on these lands.
It is arranged by nature that polar predators feast with pleasure when there is a lot of food, at the same time they are adapted for hunger strikes, if there is not enough food; but their fat reserves are not enough to survive global warming.
Polar bears use ice as platforms for hunting fish, their main prey, and if the ice disappears, the animals will have to go away in search of food and a new life.
This means that in the period of a long absence of ice, polar bears will have to calculate their strength and rely only on their own supply of fat. Perhaps they will find some food along the way, but as animals with huge energy needs, bears are likely to prey on fatty and high-calorie mammals that also live on the ice surface.
The period of lack of ice can last more than four months, and will directly affect the population of the polar bear. In search of food, predators will enter cities and villages near the Arctic. The sharp sense of smell of polar bears will lead them to landfills. It is easy to imagine that these visits will often end badly.
Human Intervention in the Life of Polar Bears
Besides the threat of climate change, another immediate danger to polar bears is the increase in offshore oil and gas production, due to the development of the Arctic Ocean. The US government recently agreed to Royal Dutch Shell to conduct exploratory drilling in the Chukchi Sea, home to one of two polar bear populations.
As for the U.S. Fish and Wildlife Service's plan to conserve the polar bear population, it is designed to save 5 polar bear species from five different regions from extinction: the USA, Canada, Denmark, Norway, and Russia.The US Environmental Protection Agency has developed a plan to save polar bears.
A team of more than 30 experts in the field of polar bears, including World Wildlife Fund staff, has been working with the Fisheries and Wildlife Protection Service over the past few years to provide polar bears with the right conditions in the event of a complete and irreversible danger.
Having already noticed the first climatic changes in nature, we have a chance to reduce or minimize the threat to the lives of many inhabitants of the Arctic right now. And the created plan will serve as a guideline for the entire team involved in the operation “Conservation of the polar bear population”.
