As the globe continues to warm, it is becoming more difficult for plants and animals to adapt to the warmer temperatures and increased stress. Polar bears face imminent threat of extinction if drastic measures are not taken to reduce greenhouse gas and carbon dioxide emissions. In its second warning on Friday, the Federal government announced that climate change is threatening Arctic sea ice in an alarming rate and leaving polar bears vulnerable to extinction.
Polar bears are among the most endangered species in the world, with about 200 left. But if these animals are not well protected, there is a real danger that many more could be lost forever.
The threat to the polar bear comes from the green house effect. When the earth’s temperature is warming up, the land absorbs more heat and loses more ice. This leaves the ground colder than it used to be, which can cause a loss of energy for plants and animals. Greenhouse gas emissions contribute to this process by trapping heat and causing the air to become warmer. If we fail to do something about the greenhouse effect, we will see a major impact on the planet and all living things.
One of the first signs of the threat to polar bears is that their habitats are drying out faster than ever. Polar bears live in thick vegetation in the Arctic that is very dense. However, as the forests begin to melt, more polar bears will be forced to seek other areas of water and food where they can survive.
In addition to losing more of their natural habitat, the green house effect is making it harder for the polar bear to reproduce. Polar bears have a special adaptation known as a sire gene. This gene makes females more likely to have a child if the mother has had one or more pregnancies in her lifetime.
Climate change has also increased the risk of disease among polar bears. A virus known as the circovirus was responsible for a recent mass die-off. Climate change is also increasing the frequency of bear attacks and fatalities. Since there are no natural predators for polar bears in Alaska, they are increasingly vulnerable to humans and their homes.
Bears are now a protected species under the Endangered Species Act. and it will take some serious action to protect them.
While the ice melts, polar bears will be forced to move northward into the open ocean, risking death if they cannot find food and sea water to sustain them. Many of these bears will starve to death, so it is crucial that people do everything they can to assist these vulnerable animals.
The Arctic is also a dangerous place for polar bears in general. The harsh weather means that the bears must adapt to the harsh conditions and it is not surprising to learn that some bears have been known to attack and injure seals, birds and other animals. This makes it increasingly difficult for polar bears to survive in the open sea.
With a growing human population in the Arctic, polar bears will be forced to share space with people. As the human settlements expand, the chances of human-bear conflicts will increase.
Bears are often the target of bear hunters. For many people, the loss of the sea ice means that the chance of a bear attack is much higher in the summertime. Even if bears can successfully escape, the possibility of human-bear confrontation increases in the summer months.
Unfortunately, climate change does not mean that polar bears have to go extinct. While sea ice is melting at an alarming rate, there are some species that are able to survive. These bears live in the arctic regions and have adapted to the changing conditions. As the effects of climate change continue to unfold, we must find a way to help the bears survive.
