When CFCs are present in the stratosphere they reacted on by ultra violet light to release a chloride ion. The ion breaks down an ozone molecule to create an oxygen molecule and ionic oxygen. The ionic oxygen releases more chloride ions to break down more ozone and CFCs
The end result is the ozone is converted to oxygen quicker than natural processes can replace it

UV radiation causes one of the carbon-chlorine bonds to break resulting in the formation of two free radicals. The chlorine radical does the damage. It reacts with ozone to from O2 and in a later reaction the chlorine radical is reformed which means that it can go on to break down more ozone.
Cl. + O3 ------> O2 + ClO.
The chlorine is reformed when it reacts with an oxygen radical from the natural decomposition of ozone.
ClO. + O. ------> Cl. + O2

Scientists hope that the holes will be completely repaired by 2050.

How do you CFCs illustrate that technical knowledge can be a double edged sword?
1. CFCs help in refrigeration but destroy the ozone layer when released into the atmosphere
Do CFCs strengthen the ozone layer?
No, the chlorine and other chemicals in CFCs (chlorofluorocarbons) destroy the ozone molecules and weaken the ozone layer.
What makes it possible for CFCs to travel up to the ozone layer and destroy ozone?
CFCs are swirled around the world by the global winds. This can take up to ten years for them to reach the lower stratosphere but when there they are still effective at destroying ozone. CFCs in fact have a lifespan in the atmosphere of between 50 and 75 years.
What layer of the atmosphere is being destroyed by certain chemicals?
The ozone layer present in the stratospheric region of the atmosphere is being destroyed by certain chemicals. These chemicals are CFCs.
Why is the CFCs and the ozone layer a concern?
CFC's and ozone layer combined is a concern. It is the problem because CFC's destroy the ozone to a great content.
How are cfcs in the upper atmosphere related to the ozone layer?
They are carried by westerlies. They destroy the ozone.
What kind of effect do CFCs - chlorofluorocarbons - have on the atmosphere?
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.

What layer of the atmosphere is most affected by fluorocarbons?
The ozone layer, which is part of the stratosphere, is the most affected by fluorocarbons. When chlorofluorocarbons or CFCs are released into the atmosphere, they migrate from the troposphere to the stratosphere after about 3 to 5 years. These CFCs destroy the ozone layer.
What can destroy the ozone?
CFCs (chlorofluorocarbons) destroy ozone in the ozone layer.
Do CFCs strengthen the ozone layer?
No, the chlorine and other chemicals in CFCs (chlorofluorocarbons) destroy the ozone molecules and weaken the ozone layer.
What is the protective layer of the atmosphere destroyed by CFCs?
ozone
How can chloroflourocarbons destroy an ozone?
Yes, CFCs can destroy the ozone layer. They react with ozone present in ozone layer and decompose it.
What makes it possible for CFCs to travel up to the ozone layer and destroy ozone?
CFCs are swirled around the world by the global winds. This can take up to ten years for them to reach the lower stratosphere but when there they are still effective at destroying ozone. CFCs in fact have a lifespan in the atmosphere of between 50 and 75 years.
What layer of the atmosphere is being destroyed by certain chemicals?
The ozone layer present in the stratospheric region of the atmosphere is being destroyed by certain chemicals. These chemicals are CFCs.
How do chlorofluorocarbons damage ozone?
See "What is causing the depletion of the ozone layer?"
Why is the CFCs and the ozone layer a concern?
CFC's and ozone layer combined is a concern. It is the problem because CFC's destroy the ozone to a great content.
