The Ozone Hole Over Antarctica
-The ozone hole located over Antarctica is the biggest ozone “hole” on the planet. Since the weather is cold, there are a lot of human-made chemicals present in the atmosphere, and because of the areas of high and low pressure the Antarctic region provides a perfect place for an ozone hole to grow and thrive during the winter months. There have been some steps taken to help the ozone hole though. In the early 1990’s, some nations agreed on the Montreal Protocol, which bans some ozone depleting substances from everyday use, but there are still chemicals and substances present that deplete the ozone layer which should also be banned. Thanks to the work of governmental agencies like the EPA and other organizations, scientists predict the ozone hole to recover in the next 50 years.
