The Copernicus monitoring service detected a hole in the ozone layer larger than Antarctica. This hole is the largest reported since 1979. This effect occurs because of the human production of CFC's used in aerosols.
Ozone protects the surface from high-powered ultra violet rays. With the lack of ozone, the concentration of Ultra Vileta radiation on the planet increases. If we add all the ecological chaos factors we can see that we are living in a period of great concern.
But the concern must generate actions to reduce the problem. But clearly, such actions are not being done.
