In 3-5 sentences, explain the difference in good and bad atmospheric ozone and how each is distributed in Earth's atmosphere.

Ozone is a gas present in the atmosphere, very important for our survival. It is the gas that makes up the ozone layer with 90% of its molecas distributed between 20-35 km in altitude.

Ozone is important for our survival because it is the only gas capable of protecting the earth's surface from type B ultraviolet radiation, which is highly harmful to living beings.

However, Ozone is a very reactive element and for this reason it can become highly toxic, destroying microorganisms and the environment.

The good ozone layer can be described as the stratosphere part of the atmosphere which protects the Earth from harmful ultraviolet radiations from the Sun. The good ozone layer is however in a serious depleting condition due to human activities.

On the other hand, bad ozone layer is the part of the troposphere which is polluted. Emissions of toxic gases from human activities is the leading cause of this kind of pollution.
