What are the most important things I should know about the ozone layer?
assistant
The ozone layer is a thin layer of gas in the stratosphere that absorbs ultraviolet radiation from the sun. This helps to protect life on Earth by blocking harmful UVB and UVA rays. Ozone depletion occurs when there is too much chlorine or bromine in the atmosphere, which can lead to increased rates of skin cancer, cataracts, and other health problems. It’s important to reduce emissions of these substances, as well as to monitor the ozone layer closely.
