What is the significance of ozone density in the Earth's atmosphere and how does it impact the environment?

Ozone density in the Earth's atmosphere is important because it acts as a shield, protecting us from harmful ultraviolet (UV) radiation from the sun. However, human activities like burning fossil fuels can deplete ozone, leading to issues like global warming and increased health risks from UV exposure. Maintaining a healthy ozone layer is crucial for a stable environment and human well-being.
