Will Global Warming Lead to the Extinction of Polar Bears? by City Tech Blogger Wei Yan

The temperature of the entire Arctic ice and water is constantly rising and many polar bears have nowhere to go and nothing to eat.  The polar bear in the picture probably starved to death.  Scientists have judged that the bear may have gone for nearly four months without food and may have traveled 750 kilometers to the north. After four months of nothing, nothing has been achieved. Finally, the bear’s fat burned until gone and the bear died of  starvation, leaving only skin and bone, like a blanket. Experts who have studied polar bears for 40 years have pointed out that this is a  polar bear that looks almost 16 years old who used to survive in the Norwegian Svalbard in the Arctic Circle.

Who murdered this bear? We did, because we are global warming. As the Arctic ice melts the bear has little or no food to eat. Consider that if one day, humans go for four months without eating, they could finally become extinct.  And the reports by climate experts say even after we have been  repeatedly warned even after we have stopped the global warming, carbon dioxide dioxide has a life cycle of 50 to 150 years. In other words, even if we reduce carbon emissions, 50 to 150 years of carbon dioxide will still be in the air. A sad annual report  issued by the International Energy Agency shows that carbon dioxide rose by 1.4% in 2017. Humans do not have any related behaviors to stop murdering species and it’s next generation.



Global warming is a human-made problem, and for many people, being indifferent to mitigating its effects and helping affected animals is unacceptable. One of the most important things we have to do is to reduce carbon emissions from now on. This is what we have to do, because the other impacts of global warming will also effect humans and nature. Science has shown that only a significant reduction in greenhouse gas emissions is enough to protect polar bears so they can live forever and give them a chance to survive. However, if you don’t want to significantly reduce carbon emissions to keep a safe home for polar bears, there are three ways to save polar bears: Keep polar bears in or near their current habitat. This requires a huge expense, but it can also make polar bears survive, and can also develop the tourism industry, so that more people can see the extraordinary charm of polar bears. Keep polar bears in the zoo or design special zoos for polar bears. This will preserve the polar bear species and provide educational opportunities for humans. But in the distant future, if the environment re-fits them to life, it will be extremely difficult to return them to nature. Bringing the polar bear to the South Pole, experts believe that the sea ice of the Antarctic will always exist. This will have a serious impact on Antarctic species such as penguins, but if polar bears can “settle” far from the penguin habitat and adapt to each other, polar bears will still survive as wild species. We can also move other Arctic species to the South Pole to increase biodiversity, although this “relocation” may have unforeseen negative effects on current biological systems.
