    In the upper atmosphere there is a concentration of Ozone which protects us and everything else from too much exposure to UV radiation (sun). Due to certain chemicals (used to be used in refrigerators) the concentration over the polar regions was greatly reduced. This was called the ozone hole. Since these chemicals were banned by international treaty, the problem is being mitigated over time.
