The total number of polar bears in the world would drop by as much as 30% in the next 35 years, according to a report. The report confirms that there is more than 70% chance that the entire population of the polar bears in the arctic region, which is presently around 26,000, would be reduced to two-third.
Polar Bear Population To Reach Two-Third Of The Present Day In Another Three Decades
The reason behind the same is global warming. Global warming causes the polar sea ices to meltdown, as a result of which the polar bears are now missing out a natural habitat. The International Union for Conservation of Nature (IUCN) has put the polar bears on the red list of endangered and threatened species. The consistent findings that are going on, have proved threats to the life of the bears. That is just the reason that the polar bears have been listed among the ‘vulnerable’ species.
Due to the melting of the ice, the polar bears are not able to feed properly. The reason behind the same is, the polar bears use platforms of ice to reach out to their prey and hunt on them. However, they are not able to, since the ice caps are mostly melting. If the reports are to be considered, then the conditions are surely not going in the ideal direction.
These bears are divided into over 19 subpopulations, each of which is keenly observed by the researchers. Out of these 19, two sub-populations are already experiencing a notable decline in their numbers and the main reason behind the same is the shrinking sea ice. The researchers have done a calculation on the basis of the satellite data and computer simulations and checked the polar bear generation length. Working out on the same, the scientists reached the conclusion that the global loss in the total number of polar bears all across the world will be more than 30%, 50% and 80% in the next three generations.
The research team concluded, stating that the findings support the potential for large declines in the number of polar bears, owing to the ocean ice losses.
