The ozone depletion has become a worldwide issue because the ozone layer protects the earth from harmful effects of solar radiation. Since 1970, scientists noticed that in certain areas of the Earth, the concentration of ozone in the stratosphere was lower than usual.
Recent scientific studies have shown that manufactured chemical products are responsible for the progressive destruction of the stratospheric ozone layer.
What is the ozone layer?
It is a protective layer of the atmosphere that can preserve life on earth and acts as a shield to protect the earth from harmful ultraviolet radiation from the sun.
Where is it located?
The ozone layer is located in the lower portion of the stratosphere, approximately 14 to 45 kilometers above the surface of the earth.
Who discovered it?
The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. The ozone hole was discovered by British physicists when they realized that during 1985, the ozone levels had dropped to 10% below normal January levels for Antarctica.
Why we need to protect the ozone layer
We need to protect the ozone layer because it acts as a shield that absorbs ultraviolet sun rays, which can produce harmful effects on humans, such as cancer, skin aging, blindness, among other things.
