I'm looking for information on the ozone layer and the effects of pollution on it.

The ozone layer is a thin layer of gas in Earth's atmosphere that absorbs most ultraviolet (UV) radiation from the sun. It is made up of three main components: O3, NO2, and ClO. When these gases are combined they form Ozone (O3). This protective layer helps to shield us from harmful UV radiation which can cause skin cancer, cataracts, and other health problems. However, human activities such as burning fossil fuels, aerosol spray cans, and air conditioning have caused levels of Ozone in the atmosphere to decrease over time. This has led to an increase in UV radiation reaching the surface of the planet and increased risk of skin cancer.
