During a formal debate on the hazards of air pollution, one team argues that ozone is helpful to the atmosphere, and the other team argues that it is destructive. Explain why both teams are correct.
Please write clear.
In the above debate both the teams are correct in their saying. Ozone is trace gas of the atmosphere whose concentration is around 0.15 parts per million and the maximum concentration does not cross 15-20 ppm in the stratosphere.
The Ozone present in the upper levels of stratosphere makes a layer, at around 25 kilometers altitude, which is helpful for us. This layer absorbs maximum of the hazardous Ultraviolet Radiation of the sun, preventing it from reaching to surface. This is the reason why life is possible on Earth. Ultraviolet radiation is very dangerous for tissue. So that's why the first team is correct.
In the other hand Ozone present in the lower levels of atmosphere namely the Troposphere Ozone is a hazardous pollutant. It forms a part of the Urban Smog in highly polluted cities. High levels of ozone concentration in lower atmosphere are very harmful to our respiratory system. It can damage our soft tissues of eyes, nose, and whole respiratory system. So that is the reason the second team is also correct. So we can say upper atmosphere Ozone is helpful, whereas the lower atmosphere Ozone is harmful.
