I doubt they do because they are supposed to reduce and help global warming.
The magic 8 ball says: "My sources say No." No one knows where that particular "feature" is going. The record largest ozone hole was 2007, and the ozone hole for 2008 was not much smaller. The amount of UV-B that arrives at Earth's surface varies by year, and by 11 year solar cycle. Effects that are believed to be closely tied to the amount of UV-B that arrives on Earth's surface show a long-term upward trend. Plants absorb water vapor, and produce oxygen. What we do to plants, we do to the ozone layer (as much as we do anything to the ozone layer).
See "What does the ozone layer do?" in the "Related questions" section below.
If the ozone layer vanished, there would be no life on earth. It is because the ozone layer protects us from the harmful and fatal UV radiations of the sun.
If the ozone in the ozone layer is depleted then, more UV will enter the earth. This will cause damage to life on earth.
Ozone layer is destroyed by the CFC gases released. It is also depleted because of industrial released gases.
Holes in ozone layer is the thinning of ozone layer. It is because of use of ODS by humans.
The holes in ozone are not actually holes. They are lowered concentration of ozone.
Holes in ozone layer are the thinning of ozone layer. They cause loss of life of flora and fauna.
The holes in the ozone layer is not actually a hole. It is the thinning the ozone layer below a certain concentration.
The holes in ozone layer is the thinning of ozone. It is caused by CFC's.
To prevent holes in ozone layer, we have to prevent the use of CFC chemical in our environment.
The Ozone Hole present in the ozone layer over the antarctic region is not actually a hole. It is the the thinning of the ozone layer below a certain level which is defined as the ozone hole. The formation and depletion of ozone is a natural ongoing process because of which the ozone layer keeps intact in the stratospheric region. However due to the use of CFC's the rate of formation is ozone is lesser than the depletion i.e. the CFC's are depleting more of ozone to make the ozone hole go bigger day by day.
The ozone layer is not getting holes it it. Rather the concentration is falling below a certain level, which is defined as the ozone hole.
Ozone hole is the term. It is the thinning of ozone layer.
The thinning of ozone layer is called the ozone hole. IT is caused due to CFC's.
Poking holes in ozone layer is a problem. A hole in ozone would cause the ultraviolet radiations to enter the surface.
There is only a single layer in the ozone. No multiple layers exists.
