The Ozone Hole

Air pollution is getting worse and worse. If this continues, the air quality will get to the point where it's dangerous to breathe in. Air pollution is causing a large hole in the ozone layer. Which is a layer of gases in the stratosphere. The hole is right over Antarctica. By definition the ozone layer shield refers to a region of the Earth's stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation. It contains high concentrations of ozone (O₃). The Sun's UV rays are very harmful, if this ozone hole gets really big... it's not going to be good. In 2010, the ozone hole was about 22 million square kilometers. To put that in context that's slightly smaller than North America which is about 25 million square kilometers. Imagine how big the ozone hole will be in 50 years; I don't want to.
