Apparently, there is a major improvement in the healing of the ozone layer around the Antarctic Region. This may be due to the Montreal Protocol made in 1987 to stop producing ozone-depleting substances (ODSs) that could be responsible for the change or reversing of the air currents that can deplete these layers. Two major examples of these substances are aerosols and CFCs (Chlorofluorocarbons).
Researchers have found that the pausing of the jet streams that swirl around the poles of the earth was caused due to ozone depletion which led to the lack of rainfall in Australia for the past three decades. But even so, there is still high levels of carbon dioxide that continue to creep upwards; depriving our accomplishments.
The Montreal Protocol shows us insight on what would happen if we take global and immediate action to help in reversing some of the damage that we have started. However, it is pretty evident that the emission of greenhouse gases is a reminder that one action isn’t enough to make a change.
