The ozone layer can be found on the Earth’s Stratosphere. It is essential for mankind because it absorbs the UV radiation from the sun and shield us from it.
However, humans use a lot of products that will deplete the ozone layer. Such products releases ozone-depleting chemicals such as CFCs. This is terrible.
Fortunately, if we cooperate and cut down on ozone-depleting products, we can protect our ozone layer. The Montreal Protocol on Substances that Deplete the Ozone Layer is an international treaty which includes phasing out the production of numerous substances that are responsible for ozone depletion. Since then, the atmospheric concentrations of the most important chlorofluorocarbons and related chlorinated hydrocarbons have either leveled off or decreased. We have made improvements!
Let us do our part to protect our Earth.
