Yes, scientists know what is causing the ozone layer to disappear. It is the continues use of ozone depleting substances.
No humans don't cause the ozone layer, however some of the chemicals we use is causing parts of this layer to disappear.
Absolutely! Scientists have observed the "hole" that occurs over the Antarctic for several decades now as it appears at the same time at the end if each winter period. We realize that the thinning area that we call the hole happens very naturally due to the lack of sun in that area. This is why the area disappears shortly after the long winter night ends. We also know that solar mass ejections can seriously damage this ozone layer. There is strong evidence that solar ejections in the 1800's caused far more damage to the ozone layer then at any other time in recorded history. Today the layer faces another issue. That is man made chemicals referred to as CFC's. Some people believe that these gases are climbing into our stratosphere and causing additional thinning.
The ozone layer doesn't disappear in near future. It depends upon how CFC's are released in future.
The increase in Uv rays. They noticed the UV pattern.
ozone layer disappears due to man made chemicals. These are CFC's that damage the ozone layer.
Scientists hope the ozone layer will have recovered by around 2050.
There is an ozone layer. Scientists have confirmed that.
CFC's are causing loss of ozone layer. They react with ozone to deplete it.
CFC's are causing damage to ozone layer. They react with ozone to deplete it.
the crust because that is the layer we live on so scientists can study it more thourouly

The ozone layer has a hole.It was proven by scientists.
