Why is the ozone layer depleting?
assistant
The ozone layer is a protective layer of gas in the stratosphere that absorbs UV radiation from the sun. It’s made up of three main gases: Ozone, nitrogen dioxide and carbon dioxide. Ozone is created by sunlight breaking down oxygen molecules, and it helps to protect us from harmful UV radiation. However, when there are high levels of ozone in the atmosphere, it can break down into other chemicals such as nitrogen oxides, which react with other compounds to form ground-level ozone. This can lead to health problems for people living near cities and industrial areas.
