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.
We can prevent the thinning of ozone layer by curbing the use of ozone depleting substances. These ODS contain compounds which react with ozone in the ozone layer and deplete it.
To prevent holes in ozone layer, we have to prevent the use of CFC chemical in our environment.
The ozone layer cannot be prevented. However the ozone hole can be.
To prevent the thinning of ozone layer, we must:Plant more and more treesAvoid the usage of CFC's.
We do not want to prevent the ozone. It protects us.
Gaps in ozone layer is ozone hole. Curbing the use of CFC's can heal it.
To prevent the destruction of ozone layer, we should minimize the use of ozone depleting substances. These substances are the one that react with ozone and deplete it.
Ozone layer is a pool of ozone molecule. It is being destroyed by CFC's.
To prevent damage, curb the CFC's. They react with ozone and deplete it.
Ozone depleting substances or ODS are the ones that are destroying the ozone layer. in order to prevent this depletion, what humans can do is to minimize their use so as to allow ozone to replenish itself.
To prevent causing holes in ozone layer, we must stop the use of CFC's. They react with ozone to deplete it.
To prevent ozone depletion, we have to:Do afforestationStop the use of CFC products.
