As endeavours of human beings in preventing damage to the ozone layer achieved success as expected, it is potential for recovering the ozone layer in coming decades, according to recent press releases of the United Nations.

An international convention signed by global countries in 1987 to stop the use of chemicals harming the ozone layer became one of the factors to recover the ozone layer, according to the analyses.

Naturally, the ozone layer can absorb 97-99 per cent of ul­traviolet rays from the sunray which can harm all living beings including humans. As it naturally prevents the dangerous impacts of ultraviolet rays, the ozone layer is invaluable for all living beings inhabiting throughout the world.

Ozone layer depletion based on various reasons will be weak to absorb the ultravio­let ray. If so, such a dangerous ray will fall on the world with­out any hindrances. In conse­quence, all human beings will face pandemic impacts. Skins of human beings will suffer from blisters and subsequent diseases. The withering of var­ious plants may cause discon­nection of food supply chains, and it will happen starvation and famine. As such, it would not be easy for the standing of human beings across the world, according to the pre­dictions of scientists.

In this regard, all global countries are responsible for the prevention of damage to the ozone layer in the strato­sphere which is located from 12 miles to 19 miles above the world.

Currently, ozone lay­er depletion becomes a main problem related to the envi­ronment similar to problems of climate change, air, water, and soil pollution, soil degra­dation, deforestation, deser­tification, and disappearance of biodiversity.

Scientists have noticed that chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) are harming the ozone layer since the 1970s. Hence, the United Nations led the promulgation of international conventions as the ozone layer depletion based on refrigeration facilities in the majority of global countries becomes a primary challenge for current environmental conservation.

Thanks to following the 1985 Vienna Convention for the Pro­tection of the Ozone Layer and the 1983 Montreal Protocol on Substances that Deplete the Ozone Layer, the thin ozone layer could be thick. So, scientists predicted that the situation of the ozone layer in 2050 would be similar to that of 1980.

As the ozone layer will not exit the world, human beings are not easy to stand alive. So, relevant governments are to continue control of manufacturing elements that can cause damage to the ozone layer. If not, the thinning layer of ozone will lead to the depletion of all human beings.
