Ozone in the atmosphere can either be stratospheric (high level) or tropospheric (ground level). Stratospheric ozone is reduced by the presence of chlorine ions from CFCs. This impact can be reduced by limiting the amount of CFCs produced, used or lost. Ground level ozone is due to atmospheric down washing of stratospheric ozone by winds passing over mountains (which we can do nothing about). It is also produced by the action of ultraviolet light on a NOx/hydrocarbon mixture in the atmosphere. These can be reduced by reducing the emissions to these compounds from human activities.
Human beings are largely responsible or share a part in the depletion of ozone layer in the stratosphere.
Some of the activities which have led to this depletion are:
- The use of enormous amount of CFC's in various forms such as the aerosol cans, refrigerators, deodorants, air conditioners etc.
- The rockets or jets which fly in the stratosphere release a number of gases which in turn can deplete ozone.
- Because of the ever-growing industries all over the globe the amount of greenhouse gases which are released from these industries account for the greenhouse effect which is indirectly related to the ozone depletion.
That said, a recent edition of Time magazine stated that the 20+ year ban on chlorofluorocarbons has been effective, and the "hole" in the ozone layer at the South Pole has largely closed. An environmental disaster avoided in time by conscious effort of man. Score one for environmental responsibility.
A:CFCs and related halocarbon gases (all man-made) are the main cause of ozone depletion all over the world. CFCs released from Western countries take several years to reach the stratosphere where the ozone layer is. During that time winds spread them all over the world. In the presence of ultraviolet light these gases release chlorine and bromine atoms which destroy some of the ozone in the ozone layer. This is called ozone depletion. A:Pollution. Smog, Vehicle Emissions, Aerosols Sprays, CFC's from styrofoam & plastic. Burning of Hazardous or certain chemicals that produce CFC's . A:- Rockets into space poke holes in it.
- Aircraft cause it to thin.
- Combustion exhaust and cooling towers cause it to thin.
- Older refrigerants cause it to thin.
- Cutting down forests causes it to thin.
Pollution. Smog, Vehicle Emissions, Aerosols Sprays, CFC's from styrofoam & plastic. Burning of Hazardous or certain chemicals that produce CFC's .
The continues usage of CFC chemicals is responsible for lower level of ozone. They are one of the ozone depleting substances.
The use of CFC's reduce ozone in atmosphere. They react with ozone to deplete it.
The main activity that leads to the ozone depletion is the use of CFC by humans. These contain chemicals which react with ozone to deplete it.

How will the ozone layer depletion be catastrophic?
The ozone depletion will be catastrophic. It is because it will cause human race to extinct.
What are possible causes and effects of ozone depletion?
Possible causes of ozone depletion include human activities releasing chemicals like CFCs into the atmosphere, which break down ozone molecules. Effects of ozone depletion can lead to increased UV radiation reaching Earth's surface, posing risks to human health such as skin cancer and cataracts, as well as harm to ecosystems and wildlife.
Ozone depletion in the stratosphere is what type of problem?
Ozone depletion in the stratosphere is an environmental problem. It is primarily caused by human activities that release substances like chlorofluorocarbons (CFCs) that destroy the ozone layer, leading to increased exposure to harmful ultraviolet radiation. This depletion can have wide-ranging impacts on ecosystems, human health, and the environment.
Can carbon dioxide cause the depletion of the ozone layer?
Carbon dioxide can cause the depletion of ozone indirectly. It is due to the global warming which then causes ozone depletion.
Is global warming a factor that cause ozone depletion or a result of ozone depletion?
Global warming and ozone depletion are not related.
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.
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.
How will the ozone layer depletion be catastrophic?
The ozone depletion will be catastrophic. It is because it will cause human race to extinct.
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.
What is the mjor cause of the ozone depletion?
The major cause of ozone depletion is the reaction of CFC with ozone. They decompose ozone and cause its depletion.
What natural factors contribute to ozone depletion?
Various natural activities also cause ozone depletion. Volcanic eruptions being the highest of them.
Is volcanoes responsible for ozone depletion?
yeah but not really...it's mostly human activities
What are possible causes and effects of ozone depletion?
Possible causes of ozone depletion include human activities releasing chemicals like CFCs into the atmosphere, which break down ozone molecules. Effects of ozone depletion can lead to increased UV radiation reaching Earth's surface, posing risks to human health such as skin cancer and cataracts, as well as harm to ecosystems and wildlife.
What pollutants cause ozone depletion?
Greenhouse gases cause ozone depletion. They react with ozone to decompose it.
What can CFCs cause ozone depletion?
CFC's react with ozone to cause depletion. they decompose the ozone layer.
Why is ozone depletion and acide rain a concern?
Ozone depletion and acid rain are big concerns. They cause various ill effects on human population.
What causes the depletion of the ozone?
CFC's cause depletion of ozone. It reacts with ozone to deplete it.
