[AI-generated answer — Bot GPT 3.5]

Ozone is a gas composed of molecules with three oxygen atoms. It is produced naturally in the upper atmosphere by the interaction of sunlight with oxygen molecules. Ozone is also formed at ground level through chemical reactions involving pollutants emitted by human activities such as fossil fuel burning, industrial processes, and vehicle emissions. Ozone is an important component of the Earth's atmosphere as it plays a crucial role in filtering harmful ultraviolet (UV) radiation from the sun. However, at ground level, high concentrations of ozone can be harmful to both human health and the environment.
