The Ozone layer or also known as the Ozone shield is a delicate layer of gas in the Earth’s stratosphere that absorbs most of the Sun’s ultraviolet rays. These rays can cause numerous skin diseases. The Ozone layer is a piece of the atmosphere that has high ozone concentrations. Ozone is a gas that is made of three oxygen atoms O3. Depending on where the ozone layer is, it can either harm life or protect life on Earth.
Most of the ozone stays within the stratosphere whereby it acts as a shield, protecting the surface of the Earth from the harmful ultraviolet radiation of the sun. If this shield was to weaken, we would all be more susceptible to impaired immune systems, cataracts, and skin cancer.
Several commonly used chemicals are extremely affecting the ozone layer and causing depletion year over year. Life on Earth would not be possible without sunlight, but the energy emanating from the sun would be too much for life on Earth to thrive were it not for the ozone layer. This stratospheric layer shields Earth from most of the sun’s harmful ultraviolet radiation.
World Ozone Day is observed on September 16, every year. It is celebrated to spread awareness about the depletion of the Ozone Layer and search for possible solutions to preserve it. On today's date, people from all over the world are expected to join the Montreal protocol to join the talks and seminars. we believe you have also taken part in some activity to learn and spread the concerns and solutions about protecting the ozone layer.
“Ozone for life” is the slogan for World Ozone Day 2020. This year, we celebrate 35 years of global ozone layer protection. The slogan of the day, “Ozone for life”, reminds us that ozone is crucial for our life on Earth and we must continue to protect the ozone layer for our future generations also.
The ozone layer absorbs harmful ultraviolet radiation from the sun but this protective layer is slowly destroyed by industrial gases that slowly drift up from the earth's surface including CFCs (chlorofluorocarbons) contained in refrigerants, foaming agents, and, earlier, propellants in aerosol sprays. Discovery of the 'ozone hole' above high latitudes in the 1980s provided final evidence of the importance of ozone depletion. By 1985, countries had signed the Vienna Convention, which pledged to reduce CFCs and other ozone-depleting substances. Two years later, they signed the Montreal Protocol that laid out a plan of action.
And not so long ago, an Ozone hole of 10 times the size of Greenland was discovered. Though the hole has now been healed and closed, it leaves behind concerned and questionable discussions on the Ozone layer destruction caused by multiple human activities, and it is time to reverse climate change and ozone layer depletion.
You can help reverse this loss.
Trees mitigate the greenhouse gas effect by trapping heat, reduce ground-level ozone level, and release life-giving oxygen. We can make a difference together. Simple changes you make can have a direct and positive impact on reducing our carbon output.
