Effects of Global Warming on Polar Bears
The polar bears and other Arctic animal species are becoming an endangered species, since the glaciers have been melting as a result of global warming. The article below elaborates on the effects of global warming on polar bears.
- Polar bears are known as the world's largest land carnivore.
- Being native to the Arctic, these animals are prone to live on the ice and the sea. Thus, the melting of the glaciers is destroying their habitat.
- Not just that, they are also being exposed to starvation, since these carnivorous animals mostly feed on seals, walruses, and whales, which are also disappearing with the change in climate.
- Moreover, the food that they eat have a high degree of pollutants, which leads to birth defects and reduction in the immunity of these bears.
- Most polar bears have lost their lives by drowning while the ice glaciers melt, because the ice caps retreat before their seasonal time to which the animals are not habituated.
- The drowning is not due to the fact that these polar bears cannot swim; they can actually swim for miles together, but they are used to swimming between ice sheets, and the absence of ice sheets make them susceptible.
- The death rate of polar bears has increased manifold with rate of ice retreat being on a constant increase.
- The distance between survival and extinction is ever-increasing and that has also started showing statistically as the number of polar bears are decreasing.
- Most of the time, it happens so that before these bears can actually hoard enough food for themselves and come back to a safe place, the ice melts and catches them at a vulnerable position.
- Polar bears hunt seals as well, the number of which is also on the verge of a decline.
- Also, due to acidification of oceans, the marine animals are consuming contaminated food, which in turn is passed onto the polar bears who feed on them, thus weakening their immune systems and also leading to birth defects.
- The answer is " No" of we think from the point of view of finding a solution for global warming, but there is definitely a gleam of hope that can be seen, since these animals are trying to adapt to the changing climatic conditions.
- The younger bears seem to be able to sustain on the beaches and are also found near the carcasses of whales butchered by humans, which is quite unlike polar bears.
