The Earth is changing day by day and in some cases, it is getting worse. Some animals are having trouble adjusting to the new climate conditions. Climate change has been an important factor and has damaged a lot of areas including the polar area.
Many animals are going to be extinct in the near future due to the rise of sea levels and higher temperatures. The rising temperatures are affecting the sea ice levels which are getting smaller and smaller. The sea ice is melting and specialists warn people that in the next centuries there might be no ice left in some areas.
These are some of the factors that affect animals too. For instance, some of the animals that are affected by climate change are the polar bears. The polar bear population is getting smaller and smaller because they are losing their habitat and they will soon lose their food, too.
Sea ice is the best habitat for young bears that don’t know how to swim. They stay on the ice and catch fish. If the ice continues to melt at this rate, in the next 35 year more than 30% of the polar bear population will be lost.
This research made experts think about the fact that these animals are in danger. This is why IUCN decided to classify the polar bear population as vulnerable. This is only a small step to saving these animals.
The researchers who completed this study did not focus only on one group of polar bears, they analyzed all of them. There are 19 polar bear groupings all across the Arctic. The researchers were able to determine that climate change is affecting all of them because the ice sea is the thing that is keeping them alive.
The biggest problem is that during the summer there might be no ice left. This prediction is set for 2030. This means that in almost 10 years there will be no ice left during the summer. Experts predict that maybe during the winter there will be some ice. This will affect all polar animals not only the polar bear population.
Greenhouse gasses are also affecting the polar bear population. In the last 30 years, experts have found traces of toxic PCPs in the organs and tissues of female bears and their pups. All of these factors are affecting and threatening the lives of these animals.
