The action already taken is to ban the production of CFC gases for industrial use. The impact of this has been to reverse the trend to ozone depletion, and the Antarctic ozone hole has been diminishing since 2006. This is evidence that humans can damage the environment on a global scale, and also that humans can repair that damage by concerted effort.
Contaminants such as water vapor (Nature and Man), CFCs (Man), and bromine compounds (Nature and Man) cause the equilibrium concentration of ozone to decrease. This makes the ozone hole (once it forms) to be larger, as compared to ages when these contaminants were not present.
The ozone hole is a natural occurrence. You cannot prevent it. You might keep it from starting sooner, have more ozone in it, or from lasting longer.... but you cannot stop it from forming once a year at each pole when it is late winter / early spring there.
The only areas that have a thinning are (referred to as the hole) is near each pole when it is in their winter phase. The sun is unable to keep up production of ozone. No noticeable change occurs where the sun can hit this area all of the year.
The hole is caused by a lack of sunlight reaching the oxygen in the stratosphere. It is also caused by chlorofluorocarbons (CFCs). Ozone is an unstable gas that decays into oxygen when there is no energy to keep it bound. The ozone hole occurs in later winter / early spring, when visible light hits the atmosphere of the hole, but UV-C has been filtered out by atmosphere elsewhere. So contaminants like CFCs that need visible light to photocatalytically destroy ozone get what they need, but new ozone is not made.
Ozone is a naturally occurring greenhouse gas that helps keep the earth warm. Therefore the depletion of the ozone layer had a minor cooling effect on the world, although more than compensated for by the rise in carbon dioxide levels. Because the depletion was concentrated in the Antarctic region, this is believed to have contributed to altered wind wind patterns. The main problem with depletion of the ozone layer was not so much any effect on the weather, but the potential effect on our health, through excessive exposure to ultraviolet light.

No, as the f(x) values keep getting larger as x gets larger.
No. Ozone is a very unstable gas and is found fairly uniformly throughout the planet. The "hole" found at each pole occurs only during the winter at each pole. If we could produce enough ozone and insert i into the area that is thin, we would see it degrade into oxygen in a few days. The layer needs the sun, which is not present during their winter months, to keep the ozone active and not decay into oxygen.

Man can keep environment ozone friendly. It is by curbing the use of CFC's.

They have a blow hole on top of their head/back It can open and close to breath in and out, and to keep the water from getting in.
You would never want to prevent the ozone layer. This is needed to keep life tolerable on the planet. Without this 3 mm thick layer of gas we would have too much UV-B hitting our planet. If you are asking how to prevent the "hole" in the ozone that occurs for short periods each year. This can't be stopped as it is from the angle of our planet versus the sun. When sunlight cannot reach the ozone layer, the ozone decays into oxygen.
Destruction of ozone by CFC's is a great deal of worry. They decompose and keep on depleting ozone.
Chlorine depletes the ozone layer. We have to keep its amount in check.
