The issues would require that there be a problem if depleting ozone. The ozone layer does have two holes in it. One is over the Antarctic at the end of the winter when the sun has not created any ozone for months. The other thinning area is referred to as the dimple because it is so small and over the Arctic during it's winter. Both are due to a lack of sun during the winter months.
The hole is much smaller today then in 1858 which was the largest recorded thinning of the ozone layer. This was before CFC's and due exclusively to solar flares.
The current environmentalist claim to your ability to help the ozone layer though is to not use aerosols, not use air conditioning and generally avoid CFC's.

What has caused ozone to increase?
Ozone is increased by various natural factors. Thunders and UV are some of them.
What activities of man contribute to the depletion of ozone layer?
In the 1970s humans released CFCs into the atmosphere. It was used as a gas in aerosol cans, refrigerators and air conditioners. Production of CFCs was phased out after the Montreal Protocol in 1989. Scientists hope the ozone layer will be repaired around 2050.
What is ozone thinning?
This is a thinning (by about 2/3, of the ozone over the Antarctic during the spring time, towards the end of the long winter night in the south pole. There is no actual hole in the layer. This has occurred for centuries, in fact the thinnest we know the layer has ever been is in 1858, before man started using cfc's. A similar thinning occurs, to a much smaller extent in the Arctic during the end of it's winter night also. The thinning is much smaller in the Arctic and NASA even reffers to this thin area as the "Dimple" due to the small size.
What should you do to prevent the occurrence of ozone depletion?
Ozone depletion is a serious threat to human race in the recent times. Ozone layer which protects us from the harmful ultraviolet rays of sun is thinning and thus the harmful rays are coming towards the earth and thus causing problems like skin cancer in humans. Moreover problems like floods, global warming are also related with ozone depletion. The steps which could be taken to prevent ozone depletion are : 1) Do not use excessive deodorants as they contain CFC's which can harm the ozone layer. 2)Do not keep refrigerators open for long time. 2)Fire extinguishers must be made minimum in use 3)Air conditions must be properly checked as old air conditions release CFC's. 4) The use of Aerosol cans must be minimized.
What are the solutions to the problem of ozone depletion?
We could stop making chemicals that destroy ozone. We could stop buying products that are made in countries that are not bound by agreements to reduce or eliminate ozone destroying chemicals. About 2/3 of the man-made ozone destruction is related to CFC-11 and CFC-12.

What are some of the possible effects the depletion of the ozone layer?
Due to ozone depletion the harmful UV radiations enter the earth and cause a number of problems. Some of them are: 1) UV radiations cause skin cancer,eye cataract and suppression of immune system. 2) Photoplankons, the base of most of the food chains are destroyed by these radiations. 3) Ozone depletion leads to Global Warming which increases the global temperature of the surface of earth.

Consequences of ozone depletion?
The life of our planet depends on this 3 mm layer of a very reactive gos. Without this layer life on our planet would die off. That is why radicals are able to scare people into actions that may or may not help and scientifically questionable issue. We know the hole is not a hole, but a thin area that occurs naturally. What scientists are questioning is whether or not a small portion of the thinning may not be natural but induced by some very reactive gases that man has added into our atmosphere.An honest answer is that we do not know. What we do know is it is a needed layer and that this thinning has occurred for generations.
How can you protect antarctica from the ozone hole in point form ways please?
1) Minimize the use of CFC's i.e. chlorofluorocarbons because they are the ones resulting in the maximum ozone depletion 2) The flight of rockets in the layers of atmosphere specially the stratospheric layer should be controlled. 3) The vehicles should be checked for pollution specially in the continents near Antarctica because the winds carry the greenhouse gases to the poles which cause the global warming as well as the ozone depletion.
What can you do to prevent the further thinning of the ozone layer?
Further damage of ozone can be reduced. This can be done by banning the use of CFCs. Ban on CFCs can help it. Furthermore planting more trees would help to the cause. Humans can stop ozone depletion. They can stop this by curbing use of CFCs. Do not use aerosol sprays, as they contain the chlorofluorocarbons that destroy the ozone layer. Some refrigerators also contain CFCs, so look for energy star fridges. In order to prevent further destruction of ozone layer, we must curb the use of ozone depleting substances which release CFCs. Some of the items which contain CFCs are deodorants, aerosol sprays, refrigerators. Yes, we can prevent further depletion of ozone layer by reducing the use of ozone depleting substances. These substances contain CFCs which initiate the process of ozone depletion.
How do you reduce ozone depletion?
Many things can be done to prevent depletion of the Ozone (Ozone Layer) (a little background...) Ozone is comprised of 3 oxygen atoms, known as O3. When we hear the term Oxygen, it is usually referring to the Oxygen that we breathe, known as O2. O2 is a necessary component for life (almost all life) on Earth's surface - it is the form of Oxygen that we breathe; it is used in cellular respiration in animals and photosynthesis in plants. Ozone, or O3, is in fact toxic to living creatures, but without it we would be in a lot of danger - So how does that work? Ozone, is naturally found in the upper level of our atmosphere. It absorbs many of the harmful rays of the sun, known as Ultraviolet radiation (UV-A, UV-B and UV-C) which can cause cancer and cellular damage. Pollution is a major source of depletion of the Ozone layer. Many man-made pollutants contain compounds called Chlorofluorocarbons (CFCs) and bromofluorocarbons. These compounnds can rise to the upper level of our stratosphere Where UV light breaks them into free radicals of Chlorine (Cl) and Bromine (Br). Each of these radicals is then free to react with O3 and catalyze a chain reaction capable of breaking down over 10,000 ozone molecules. IN SHORT- the compounds in Pollution from factories and aerosol cans can destroy ozone molecules, To prevent this laws have been passed to stop and control production of these compounds. You as an individual can help by lobbying in Congress, supporting environmental organizations and spreading the word to your friends, family and anyone you know about the causes and prevention of damage to Ozone.
Why has the contribution of chlorine in the destruction of stratospheric ozone increased significantly since the 1970s?
There is no unequivocal evidence that such an occurance (sudden uptick in ozone depletion) is correct, whether based on chlorine or not. We were barely aware of the ozone layer in the 1970's, having just detected evidence of depletion (and since finding out that depletion may have been ongoing since before the early 1700s), and finally finding out that an ozone hole forms (once each year, when it is winter at the poles). The chlorine compounds in the "ozone hole" have been identified as about 3% from natural sources, 15% chloromethane (natural, and Man-caused), and 82% from CFCs (which do not occur in Nature). CFCs have been in use since the early 1900s, and there is little indication that they have been only liberated in the 1970's. It is more likely that they have been steadily liberated, and steadily increasing, and constantly accumulating in the ozone layer... the only place in Nature where something can destroy them.
Can you describe the process of the ozone depletion?
The ozone depletion process begins when CFCs and other ozone-depleting substances (ODS) are emitted into the atmosphere(1). Winds efficiently mix the troposphere and evenly distribute the gases. CFCs are extremely stable, and they do not dissolve in rain. After a period of several years, ODS molecules reach the stratosphere, about 10 kilometers above the Earth's surface (2). Strong UV light breaks apart the ODS molecule. CFCs, HCFCs, carbon tetrachloride, methyl chloroform, and other gases release chlorine atoms, and halons and methyl bromide release bromine atoms (3). It is these atoms that actually destroy ozone, not the intact ODS molecule. It is estimated that one chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere (4).
