Most of the ozone resides in the stratosphere (a layer of the atmosphere between 10 and 40 kilometers above the earth). If the ozonosphere continues to weaken, people will become more susceptible to skin cancer, cataracts and eye damage. immune system due to the greater exposure of the body to UV rays that the Sun leaves in space.
The Montreal Protocol, since its signing, is one of the most important environmental agreements of the 20th century, reveals the UN. It is that, thanks to this global agreement, the people avoided something important health hazard due to ultraviolet radiation that can leak through the large hole that formed in the ozone layer in the early 1980s.
“He is on the way to recovery. in the next four decades,” indicates a statement from the World Meteorological Organization (WMO) published on January 9, 2023. The document also emphasizes the progressive elimination on a global scale of chemical substances that deplete of this because it contributes to mitigating climate change.climate.
This conclusion was made by various meteorological experts who, supported by the United Nations, confirmed that the progressive elimination of nearly 99% of banned substances that deplete the ozone layer managed to protect him and contributed to its remarkable recovery in the stratosphere. In addition, this global measure has helped reduce people’s exposure to harmful ultraviolet (UV) radiation from the sun.
prohibited items a set of greenhouse gases made by people which destroys the ozone layer. Among them, the UN includes chlorofluorocarbons, substances found in everyday products such as air conditioners, refrigerators and aerosol containers.
In this sense, if current care policies are maintained, The ozone layer will recover to 1980 values (before the formation of the ozone hole) in approximately 2066 in Antarctica, in 2045 in the Arctic and in 2040 in the rest of the world, WMO experts estimate.
