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).

The disadvantages of Chlorofluorocarbons is they are long lasting, 20-100 years, and they deplete the ozone layer. The ozone layer has begun to heal based on the ban of CFC as a propellant in many household products.
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.
In the last century the ozone layer was depleted. It is also termed as ozone hole.
You can find ozone in any layer of the atmosphere, but in the lower layers it does not last long. The so-called ozone layer is in the lower portion of the stratosphere, at a height where it takes a long time to dissociate.

In the Precambrian time, 4.6 billion yrs. ago
Ozone layer contains ozone in it. Therefore, it is named so.
Ozone layer is formed of ozone. It is a gas.
Earth has a layer of ozone. It is present as the ozone layer.
damage to ozone layer is called ozone depletion. It is thinning of ozone layer.
Ozone is a layer which protects us. Actually ozone is just a gas, ozone layer is the layer.
The Ozone Layer, which is made up of Ozone molecules, or O3 molecules, occurs in the stratosphere. The stratosphere is the second layer up from the surface, above the troposphere, which we live in. (Sorry...long drawn out answer.) :)
The layer of gases that surround the atmosphere is ozone. It is present as the ozone layer.
Ozone layer is the layer of ozone. Humans are altering it by CFC's.
