Arctic animals have always been walking the tightrope in terms of population. The effect of global warming and climatic changes upon these animals is nothing new, and polar bears are a species that have been standing closer to the danger zone. Revelations of a new study are even more painful than we might have thought.
Biologists from the U.S. Geological Survey (USGS) say that the climatic change across the poles due to global warming has been causing further threats to these animals rather than just to the habitat.
Besides the undesirable change of climate, these animals will also have to scuffle for activities like hunting, mating, and migration. And that’s due to drastic increase in the rate at which sea ice is melting.
According to the reports from US Fish and Wildlife Service, these animals rely upon the sea ice to swift through the ocean. This is also the most preferred method of polar bears for hunting down their food, and for travelling greater distances.
However, scientists believe that these floating ice crystals are melting down at quicker rates due to the uncontrolled emission of pollutants, mostly due to the greenhouse emissions from the burning of fossil fuels.
The estimated population of polar bears is currently between 20,000 and 25,000 globally. They are also protected under the Federal Endangered Species Act. But scientists fear that there will be a steep decline in their population by 2040 if humans don’t check uncontrolled emissions. The Fish and Wildlife department will be seeking public opinion for a plan to revive the polar bear population.
