Polar Bear

In past centuries, the number of polar bears sharply declined, mainly due to warm weather. Polar bears live on ice islands, and when the ice islands decrease, they have to move to land. However, on land, they cannot find big animals to hunt, which reduces their survival rate.
For humans, if the warm weather continues, sea levels will rise, and low-lying islands may disappear in 100 years. In 2015, 145 countries gathered in Paris to discuss how to prevent global warming. China made significant contributions in this meeting by promising to reduce waste air and materials from factories.
As ordinary citizens, we may not fully understand the intricacies of climate change, but we know that a rising sea level will impact the lives of certain people.
