Scientists didn't knew ozone layer before 1880. It is because of lack of technology at that time.
Scientists hope the ozone layer will have recovered by around 2050.
In 1985, we discovered. It was done by Dr Farman.
Yes, there is. Ozone layer is replenishing.
The discovery of the hole in the ozone layer was officially announced in 1985. British scientists reported that the ozone layer above Antarctica was significantly depleted. This discovery led to global concern about the effects of ozone depletion on the environment.
The ozone layer is the portion of the atmosphere that filters out most of the dangerous UV waves that hit the Earth from the sun. In 1985, scientists discovered a very large hole in the ozone layer above Antarctica.
Scientists hope the ozone layer will have recovered by around 2050.
The ozone layer was discovered in the year 1913 by the scientists Charles Fabry and Henry Buisson.
Right after the Great Oxidation Event, when the ozone layer first formed. About 500 million years ago.
The ozone layer was discovered in the year 1985. During that period large amount of CFC's were used without knowing the adverse effect of these fatal chemicals. In 1985 scientists discovered that appreciable thinning of ozone layer is happening over the antarctic region. And thus steps for its recovery were made into action.
The ozone layer covers the entire planet twice a year, every year. That is when it is biggest.
In 1985, we discovered. It was done by Dr Farman.
Yes, there is. Ozone layer is replenishing.
The ozone layer is growing slow. This is due to ozone depletion by CFC's.

Yes, it has. Size of ozone layer changes according to the use of CFC's.
The size of ozone layer in year 2008 was moderate. It was recovering.
