There has been notisable reduction in ozone layer, particularly in the stratosphere, mostly because of human activity and it resulting depletion of ozone layer. The Antarctic ozone hole which forms each year over Antarctica is where this loss was most clearly noticed.

According to the theory that researchers may be concealing knowledge about ozone depletion. Peer reviewed publications and international evaluations like example from the world meteorological organisation and the United Nations environment programme these are open platforms for the promotion of scientific research and discoveries about ozone depletion.

The main cause of ozone depletion that is proven by scientific studies is the atmospheric release of ozone depleting substances (ODS) such as chlorofluorocarbons(CFCs). Under some circumstances, these compounds degrade ozone molecules causing the ozone layer to weaken.

But the amount of ODS in the atmosphere has significantly decreased. And this decrease of ODS results of international efforts made in the wake of the 1987 Montreal protocol, which restricted the manufacture and use of ODS. And this results in especially in areas outside of the polar region the ozone layer is beginning to rebound.

In conclusion, international efforts have contributed to reducing the consequences of ozone depletion, despite the fact that it was a major environment and issue caused by human activity. Maintaining transparency in sharing research finding and their consequences for international environmental policies, scientific community keeps an eye on the ozone layer and its recovery.
