On the 16th of September each year, it is International Day for the Preservation of the Ozone Layer. This is an important day to help us protect our planet from the damage of the Sun's harmful ultraviolet rays. The ozone layer is a special layer in Earth's atmosphere that helps protect us from getting sick from too much sun. But sometimes, too many chemicals and gases get released into the air, and these can damage the ozone layer and make it thinner. That's why it's important to look after the ozone layer – so that it can keep protecting us from too much sun. On International Day for the Preservation of the Ozone Layer, people around the world take some special steps to help protect and preserve our ozone layer. These include things like reducing the amount of pollution we produce, recycling waste, and using greener forms of energy like solar and wind. By doing our part, we can help ensure that our ozone layer lasts for generations to come!
