The ozone layer in our atmosphere is an important shield that keeps the majority of harmful radiation from the sun from the lower layers in which we live. Too much solar radiation is known to increase the risk of skin cancer.

Cigarettes have no effect on the ozone layer. But they do cause health problems like lung cancer.
Yes, chlorofluorocarbons (CFCs) have a negative effect on the ozone layer. When CFCs are released into the atmosphere, they break down and release chlorine, which can destroy ozone molecules. This depletion of the ozone layer can result in increased levels of ultraviolet (UV) radiation reaching the Earth's surface, leading to harmful effects on human health and the environment.
See "What does the ozone layer do?"
Ozone layer is present in stratosphere. It does not cause it any effect.
CFC's are destroying the ozone layer. They can also harm our health.
If affects our health in many ways. It causes skin cancer, eye cataract etc.
Ozone does have a cooling effect. It is because of its properties.
Carbon cycle has an effect on ozone layer. Carbon emissions cause greenhouse effect which causes ozone depletion.
The effect of ozone layer is same overall. The ozone depletion over one place will affect the UV in that area.
The layer that affects the earth's surface is ozone. Ozone is a layer of importance.
CFCs release chlorine and fluorine move to the ozone layer. There these elements react with ozone to form compounds and the ozone layer is depleted.
