The initial step in the depletion of stratospheric ozone by human activities is the emission of ozone‐depleting gases containing chlorine and bromine at Earth's surface. Most of these gases accumulate in the lower atmosphere because they are unreactive and do not dissolve readily in rain or snow. Eventually, the emitted gases are transported to the stratosphere where they are converted to more reactive gases containing chlorine and bromine. These more reactive gases then participate in reactions that destroy ozone. Finally, when air returns to be lower atmosphere, these reactive chlorine and bromine gases are removed from Earth's atmosphere by rain and snow.
Certain industrial processes and consumer products result in the atmospheric emission of "halogen source gases". These gases contain chlorine and bromine atoms, which are known to be harmful to the ozone layer. For example the chlorofluorocarbons (CFCs) and hydro chlorofluorocarbons (HCFCs), once used in almost all refrigeration and air conditioning systems; eventually reach the stratosphere where they are broken apart to release ozone‐depleting chlorine atoms. Other examples of human‐produced ozone‐ depleting gases are the "halons", which are used in fire extinguishers and which contain ozone -depleting bromine atoms. The production and consumption of all principal halogen source gases by human activities are regulate worldwide under the Montreal Protocol.

Is ozone depletion an activity that is responsible for the largest percentage of human-made carbon dioxide emissions?
Actually the questions must be the other way round that is the largest percentage of human-made carbon dioxide emissions responsible for ozone depletion. But still carbon dioxide is not the only reason for the ozone depletion. Various other factors such as freons, CFC's etc are responsible for ozone depletion.
Are carbon emissions going to destroy the ozone?
Yes they are. Carbon emissions cause global warming and then they cause ozone depletion.
How do human activities affect the global warming and ozone depletion?
Humans burning fossil fuels are causing global warming. This is continuing unchecked and is causing climate change. Human production of CFCs (now stopped) was responsible for ozone depletion. The ozone layer is very slowly recovering.
How will the ozone layer depletion be catastrophic?
The ozone depletion will be catastrophic. It is because it will cause human race to extinct.
How and why is the ozone dissapering?
Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen. It is disappearing due to in human activities.
What does ozone depletion potential refer?
Ozone depletion potential refers to the potential at which the ozone is depleting. Human activities are the main reason for its depletion.
Is ozone depletion an activity that is responsible for the largest percentage of human-made carbon dioxide emissions?
Actually the questions must be the other way round that is the largest percentage of human-made carbon dioxide emissions responsible for ozone depletion. But still carbon dioxide is not the only reason for the ozone depletion. Various other factors such as freons, CFC's etc are responsible for ozone depletion.
What are some human activities leading to ozone layer depletion?
The release of CFC's lead to ozone layer depletion. It reacts with ozone to deplete it.
Is volcanoes responsible for ozone depletion?
yeah but not really...it's mostly human activities
Are carbon emissions going to destroy the ozone?
Yes they are. Carbon emissions cause global warming and then they cause ozone depletion.
What activities of men contribute the depletion of the ozone layer?
The use of CFC contributed to depletion of ozone. It is because they react with ozone to decompose it.
How do human activities affect the global warming and ozone depletion?
Humans burning fossil fuels are causing global warming. This is continuing unchecked and is causing climate change. Human production of CFCs (now stopped) was responsible for ozone depletion. The ozone layer is very slowly recovering.
How will the ozone layer depletion be catastrophic?
The ozone depletion will be catastrophic. It is because it will cause human race to extinct.
How would the depletion of the ozone layer affect human health?
The depletion of ozone is in variance with human health. More UV's more deterioration.
How and why is the ozone dissapering?
Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen. It is disappearing due to in human activities.
What activities of man contribute to the depletion of the ozone layer?
The use of CFC's deplete ozone. They react with ozone.
Why are scientists. concerned about the depletion or thinning of the ozone layer?
Scientists are concerned about the ozone depletion. It is because this depletion can cause extinction of human race.
