Introduction to ozone depletion ozone is both beneficial and harmful to us near the ground, ozone forming as a result of chemical reactions involving traffic pollution and sunlight may cause a number of respiratory problems, particularly for young children.
Ozone depletion occurs when the natural balance between the production and destruction of strato-spheric ozone is tipped in favour of destruction although natural phenomena can cause temporary ozone loss, chlorine and bromine released from man-made synthetic compounds are now accepted as the main cause of this depletion.

The montreal protocol on substances that deplete the ozone layer (a protocol to the vienna convention for the protection of the ozone layer) is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. Ozone layer - introduction the ozone layer refers to the ozone within stratosphere, where over 90% of the earth's ozone resides ozone is an irritating, corrosive, colorless gas with a smell something like burning electrical wiring. Climate 101: ozone depletion today, there is widespread concern that the ozone layer is deteriorating due to the release of pollution containing one atom of chlorine can destroy more than a hundred thousand ozone molecules, according to the the us environmental protection agency. Ozone layer depletion first captured the attention of the whole world in the latter half of 1970, and since then, a lot of research has been done to find its possible effects and causes various studies have been undertaken to find out possible solutions.
