The ozone layer shows signs of rapid recovery

The ozone layer is tending to be very small and is able to restore the situation in 1980 in the middle of this century, according to a recent report by UN scientists.

Scientists have found an ozone hole above the Antarctic in the 1970s and this hole grew to a level of warning in the 1980s when there was a violent attack on CFCs. The risk of ozone depletion urged 196 countries to sign the Montreal Protocol in 1987.

The ban on the use of nearly 100 ozone-damaging compounds, such as chlorofluorocarbons (CFC) - substances used in the manufacture of refrigerators, pressure sprays and some foam packaging chemicals - According to the Montreal Protocol, it has helped to make the ozone layer that is shrinking and the hole capable of restoring the situation in 1980 around 2048.

"The Montreal Protocol signed in 1987 protected ozone from continuing to decline in the decades by controlling ozone-damaging chemicals ," the World Meteorological Organization (WMO) report. and the United Nations Environment Program (UNEP), said.

This report was made after 300 scientists of WMO and UNEP participated in assessing the ozone layer status for 4 consecutive years. However, the team also said the ozone layer would only disappear completely as early as 2073.

The ozone layer acts as a natural protective film against ultraviolet rays from the Sun, which can cause sunburns, skin cancer in humans, as well as destroying plants. Therefore, the small ozone hole will help us avoid thousands of cases of skin cancer each year.
