What are the main causes for ozone depletion?

Answer 1

the depletion of the ozone layer is mainly caused by gasses called chlorofluorocarbons (CFC)

CFC are used in some refrigerator's, aerosol's conditioner's, styrofoam container's and fire extinguisher's.

Answer 2

It was noticed in the 1970's that the ozone layer was diminishing gradually over the years. Scientists discovered that the use of Chlorofluorocarbons (CFC's) in aerosol cans was the main cause, along with other similar chemicals used in industry. In the mid 1980's, world governments signed a protocol called the Montreal Protocol to ban the use of CFC's and other ozone depleting chemicals in industry. Since then the ozone layer has still shown signs of thinning despite the end of the use of these chemicals.

Answer 3

The main cause of ozone depletion was the heavy use of CFCs in the late 20th century. They have been phased out but depletion is also caused by halons which can be found in fire extinguishers and Methyl Chloroform.

Answer 4

The ozone depletion can cause global warming. The same is reversible.

Answer 5

The depletion of ozone layer is caused by a number of ways. These are man made and natural processes.

Answer 6

Ozone layer is depleting due to release of ChloroFluoroCarbons(CFC) gases in atmosphere. It also gets depleted due to other inhuman activities and release of industrial gases.

Answer 7

The depletion of ozone layer is called by compounds called CFCs. These CFCs react with ozone in the ozone layer and deplete it.

Answer 8

The ozone is being depleted. CFC are the main cause. FREONS also deplete it.

Answer 9

The main cause of ozone depletion is the use of ozone depleting substances. These ODs contain CFCs which deplete the ozone.
