Over the last few decades, Arctic polar bears have been ubiquitous symbol of climate change. This majestic creature is on its outskirts of extinction by the end of the 21st century if global warming continues unabated.
What does the report say?
In July 2020, A recent report published, issue of Nature Climate Change predicted that most Arctic polar bears will become extinct by the year of 2100 if greenhouse gas emissions increasing constantly. Further, the report also states that polar bears are likely to experience reproductive failure in coming two decades (2040), reducing the number of offspring (young born of living organisms) 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 (Media company) 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 per cent each decade since 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 twelve thousand 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.
