Decreases in ozone were noted as early as 1978-79, associated with the ozone hole (identified in 1984).
The depletion of the ozone layer was first discovered in the late 1970s and was primarily linked to the use of man-made chemicals called chlorofluorocarbons (CFCs). This led to the landmark Montreal Protocol in 1987, an international agreement to phase out the production and use of ozone-depleting substances.

Scientists first discovered the thinning of the ozone layer over Antarctica in the 1980s, leading to the landmark Montreal Protocol in 1987 aimed at phasing out ozone-depleting substances.
There are many ozone depleting substances. These substances are the ones that can cause damage to the ozone layer.
Ozone depleting substances cause damage to the ozone layer. CFC's are greatest of them.
The ozone depleting substances are the one that react with ozone and deplete it. They are used as refrigerants on ships.
There are international agreements in place, such as the Montreal Protocol, that aim to reduce and eventually phase out the use of ozone-depleting substances. With strict adherence to these agreements, the ozone layer is expected to recover and stop depleting in the future.

Ozone depleting chemicals are CFC's. Other than Halogens are also ozone depleting.
The ozone is depleting at stratospheric level. It is due to CFC's.
The ozone depleting chemicals are CFC's. They react with ozone and deplete it.
The ozone depleting substances are the ones that deplete the ozone. They work by decomposing the ozone into its original constituents.
There are many ozone depleting substances. These substances are the ones that can cause damage to the ozone layer.

The Montreal Protocol mandates the use of non-ozone depleting substances to address the depletion of the ozone layer. It is an international agreement that aims to phase out the production and consumption of ozone-depleting substances, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), which harm the ozone layer. By transitioning to non-ozone depleting substances, countries can protect the ozone layer and mitigate the harmful effects of UV radiation on human health and the environment.
The ozone was first discovered in late 1800's. This led to discovery of ozone hole.
The ozone depleting substances are the one that react with ozone and deplete it. They are used as refrigerants on ships.
Materials depleting ozone are called ODS. They are CFC's and greenhouse gases.
