Polar bears on the verge of extinction by 2100
Over the past few decades, polar bears have been ubiquitous symbol of climate change. This majestic creature is on its verge of extinction by the end of the century if global warming continues unabated.
What does the report say?
A recent study published in July 2020 issue of Nature Climate Change predicted that most polar bears in the Arctic region will become extinct by the year 2100 if greenhouse gas emissions remain on their current track. Further, the report also states that polar bears are likely to experience reproductive failure by 2040, reducing the number of offspring needed for population maintenance.
Dr Péter Molnár, an assistant professor at the University of Toronto Scarborough who is also one of the authors of the recently published study told CNN in an interview that, “Ultimately, the bears need food and in order to have food, they need ice. But in order for them to have ice, we need to control climate change,”
The lovely creature found mainly near the poles wandering around icebergs covered with soft furs which makes them even more loveable is declining at a rate of more than 12% each decade since the 1970s. As sea ice declines they are forced to moved towards ashore where there is less productive water. On average, an adult polar bear can fast for a month but considering the current situation, they are forced to spent long months without eating. Their body requires 12000 of calories daily to maintain the body heat which is very essential to sustain in the icy region. However, due to the fact that they are not getting proper diets, their body system is getting weaker day by day and their rate of reproduction has seen a steep decline.
