OZONE "is the protective shield of the earth. It creates an ideal environment in which the entire ecosystem, including mankind, can nurture and live. At a height of about 15 to 30 kilometers above the earth's surface, like a fortress, there is a layer of ozone gas. Percent ultraviolet (UV) i.e. ultraviolet rays are absorbed in the ozone field and do not allow it to reach the earth
What is ozone and the ozone layer, how does it work
The Earth's atmosphere has 4 mantles. The second of these is the ozone layer at an altitude of 15-30 km above the Earth's surface.
Ozone is naturally occurring. Ozone is made up of three atoms of oxygen. Its chemical composition is O3. 98% of the most dangerous UV rays emitted from the sun are absorbed in this layer of ozone, which in turn prevents it from reaching the earth.
UV rays from the sun can cause skin cancer. This increases the risk of diseases like cataracts. Damage to the human immune system (SYStem), ozone provides protection from all these dangers.
Ozone research
The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henry Buson. He proved in his research that ozone is a gas formed by the addition of three atoms of oxygen, which is a very small amount in the atmosphere i.e. 0.02 percent.
Why Ozone Day is celebrated
The first ozone depletion in the Antarctic was discovered in 1985 in the world. With the spread of industrialization in the world, pollution of the earth's atmosphere began to increase. In particular, chloro fluoro carbon (CFC) gas, which is made up of atoms of chlorine, fluorine and carbon, played a key role in damaging the ozone layer.
Countries around the world then agreed to ban the use of this gas and the Montreal Protocol was signed on September 16, 1987. The United Nations declared September 16, 1994 to mark International Ozone Day. Ozone Day was first observed in 1995.
What happens when the ozone layer breaks down?
Due to the hole in this layer, the sun's ultraviolet rays will reach the earth directly. These rays increase the risk of skin cancer, malaria, cataracts and infectious diseases. The risk of disease can be greatly increased if the area of the ozone layer decreases by even 1% and ultraviolet rays reach humans by up to 2%.
Why is this layer being damaged?
Cosmetic products and sprays containing chlorofluorocarbons are being used. This damages the ozone layer.
Smoke from vehicles that do not meet smoke test standards. It contains excess carbon, which causes erosion.
Burning out the increased portion after harvest is exacerbating the carbon condition.
Apart from this, burning of plastic and rubber tires and rubbish is also damaging this layer.
Burning high-moisture coal is having the worst effect.
What a huge gap in the ozone layer
Research conducted during September 14-20 last year found that the gap in the ozone layer is about 9.6 million square miles (or 24.9 million square kilometers). It is estimated that this size is three times the size of the Americas. This conclusion was drawn from the stratosphere above the South Pole.
Earlier in the year 2018, NASA found that the ozone layer was recovering. According to NASA research, the ozone layer has improved by 20% since 2005 and since then, if the ozone layer continues to shrink at this rate, it could be completely the same by 2060.
