Ozone in the stratosphere is beneficial to life because it forms a protective layer that shields the Earth from harmful ultraviolet (UV) radiation from the sun. This layer, often referred to as the ozone layer, absorbs and scatters a significant portion of the UV radiation, preventing it from reaching the Earth's surface. This helps to reduce the risk of skin cancer, cataracts, and other health issues caused by overexposure to UV radiation.
On the other hand, ozone in the troposphere is considered a pollutant because at ground level it is a harmful component of smog. Ozone is formed when nitrogen oxides (NOx) and volatile organic compounds (VOCs) react in the presence of sunlight. These pollutants are emitted from sources such as vehicles, industrial processes, and power plants. Ground-level ozone can irritate the respiratory system, worsen asthma and other respiratory conditions, and contribute to the formation of smog, which can negatively impact air quality and human health.
Overall, the presence of ozone in the stratosphere is beneficial as it protects life on Earth from harmful UV radiation, while ozone in the troposphere is considered a pollutant because it contributes to smog and poor air quality.
