Excessive ozone in the ozone layer will decay rapidly to near current levels. It is unstable and breaks down with time. It would take a catastrophic event to make too much more than we currently do.
If the ozone layer stayed where it was, and got twice as thick, then we'd have less UV-B striking Earth's surface, fewer cataracts, fewer melanomas, probably higher crop yields. We would also face extreme global warming as ozone is a greenhouse gas. The cooing of the Antarctic is being blamed on the thinning of the ozone layer, for example.
If the atmosphere thinned, and the ozone layer was forced lower, then high levels of ozone (such as peak levels found in the ozone layer) would likely kill most life on Earth in a few decades. Mice that were forced to breathe such levels of ozone for even a day fared very poorly. Ozone is a very strong antiseptic. It is even good with humans for this purpose, so lo level ozone is not a good thing.
The ozone layer is amazing resilient though. The "hole" in the ozone layer appears twice each year during each poles winter. This is due to the lack of sunlight. Once the sun returns, the hole disappears very quickly.
What else can I help you with?
Why is halon harmful for ozone layer?
Halons are harmful for ozone. They also react with ozone to deplete it.
What ozone layer do?
Ozone layer protects us from harmful UV rays. these are harmful UV radiations of the sun.
What layer of the ozone is CFCs harmful to?
CFCs harm the ozone layer by breaking down ozone molecules in the stratosphere, specifically in the layer known as the ozone layer. This depletion of ozone molecules can lead to an increase in harmful ultraviolet radiation reaching the Earth's surface.
Which layer of the atmosphere is the ozone most harmful?
The ozone layer is most harmful in the stratosphere, the second layer of the atmosphere. It helps to protect Earth by absorbing harmful ultraviolet radiation from the sun, but ground-level ozone can be harmful to human health as a pollutant in the troposphere.
Which part of atmosphere screens out the harmful radiation from sun?
The ozone layer, which is found in the stratosphere, screens out harmful ultraviolet (UV) radiation from the sun. UV radiation is dangerous to living organisms as it can cause skin cancer and damage DNA.
At what layer is ozone harmful?
The ozone is harmful not at stratosphere. It is harmful at some layer. Te layer is troposphere.
How can ozone layer can be harmful?
Ozone layer cannot be harmful. It protects us from harmful UV rays of the sun.
Why is halon harmful for ozone layer?
Halons are harmful for ozone. They also react with ozone to deplete it.
What ozone layer do?
Ozone layer protects us from harmful UV rays. these are harmful UV radiations of the sun.
Why are chloroflurocarbons harmful to the ozone layer?
See "What is causing the depletion of the ozone layer?"
What layer of the ozone is CFCs harmful to?
CFCs harm the ozone layer by breaking down ozone molecules in the stratosphere, specifically in the layer known as the ozone layer. This depletion of ozone molecules can lead to an increase in harmful ultraviolet radiation reaching the Earth's surface.

The ozone layer, which is found in the stratosphere, screens out harmful ultraviolet (UV) radiation from the sun. UV radiation is dangerous to living organisms as it can cause skin cancer and damage DNA.
What layer of the atmosphere the ozone layer is present and absorbs harmful sun rays?
Sun rays that are harmful are protected by the ozone layer. This layer is a boon to the organisms of the earth.
What is layer in the atmostsphere where the ozone layer is found?
Ozone is found in the ozone layer. It protects us from the harmful UV rays of the sun.
Is ozone turning into oxygen a harmful or useful reaction?
It is harmful at ozone layer. It is because this leads to depletion of ozone.
Why are small quantities of chlorofluorocarbons so harmful to the ozone layer?
CFC's are harmful. They form a chain reaction in ozone layer to destroy it.
