Amidst all the not-so-good news we keep hearing about the COVID_19 situation, there’s some good news about planet earth that you would like to hear. Scientists have confirmed that the ozone layer, which we have been damaging since a long time now, keeps repairing itself.
The ozone layer, for those of you who are not sure what it is, is the protective layer around Earth that filters most of the sun’s ultraviolet radiation, thereby preventing many medical problems we will get, if exposed to it.
In 1987, a protocol was introduced for the protection and repair of the ozone layer. This protocol, called the “Montreal Protocol”, seems to be working, according to a study released this week.
The protocol aimed at step by step discontinuation of the use of specific substances that caused drastic damage to the ozone layer. The substances thus selected were generated in refrigerants, aerosol spray propellants, industrial solvents, and foam blowing agents.
Antara Banerjee, lead author of the new study, spoke about the evidence they found:
“This study adds to growing evidence showing the profound effectiveness of the Montreal Protocol. Not only has the treaty spurred healing of the ozone layer, it’s also driving recent changes in Southern Hemisphere air circulation patterns.
The challenge in this study was proving our hypothesis that ozone recovery is in fact driving these atmospheric circulation changes and it isn’t just a coincidence.”
Anyway, however good this news sounds, it does not give us any right to take this easily. We should continue to minimize our carbon footprint. One thing that has drastically reduced carbon emissions is the ongoing COVID-19 pandemic, which seems to have reduced pollution in a lot of countries around the world.
