Antarctic Ozone Layer Soon to be Restored
January 31, 2050 - Scientists now believe that the ozone layer over Antarctic will in 15 years be basically restored to the level it had in 1980. This will mean a great victory for international co-operation when it comes to the reduction of ozone-depleting gases.
In January 1989, the Montreal Protocol came in effect eventually signed by more than 160 nations, which included a timetable on which the production of several groups of halogenated hydrocarbons had to stop.
Chlorofluorocarbons (CFCs) were in 1974 recognized by Mario Molina and Sherry Rowland, chemists at the University of California, as harmful to the Earth's ozone layer, even though production of CFCs had started already in the 1920s. They were awarded with the Nobel Prize in Chemistry in 1995 due to their work.
The hole in the ozone layer over Antarctic covered at its worst an area bigger than Canada 45 years ago. The depletion varies over the seasons, but accelerate when the sunlight comes back after the winter.
Argument: According to the study When will the Antarctic ozone hole recover, the ozone layer will in year 2068 be restored to the level it had 1980.

it really is so good that the ozone is healing itself. It is a shame that global warming won't heal itself though.

Salary rises and so does the cost of wheat.
Otherwise how will the farmer and the salesperson selling the wheat make a living?
