These CFCs rise up to the atmosphere, destroying the layer. The chlorine atom of a CFC reacts with an oxygen atom of the ozone molecule, resulting in two molecules of oxygen. The ozone is destroyed.
An important long-term effect of the destruction of the ozone layer is a rise in the ultraviolet radiation near the earth. This in turn is a reason behind rising skin cancer, degrading of several substances like plastics, paints and fabrics, and reduced yield of major crops. It was reported by the Environmental Effects Panel in 1991 that the consequences of “a sustained 10% loss of ozone” would be a 26% rise in the occurrence of non-melanoma skin cancers (Anderson, Sarma and Sinclair, 31). A 1% loss would result in an increase of 100,000 to 150,000 cases of cataract-induced blindness throughout the world. The resulting rise in ultraviolet radiation would be responsible for a rise in the occurrence of melanoma.
It was due to such drastic consequences that the Montreal Protocol was set signed by 24 nations on 16th September 1987 (Maunder 38). According to this Protocol there has to be a reduction in the consumption of CFCs by particular amounts, which would greatly reduce the degree of damage

The outcome of the study suggested that the lower level of carbon dioxide gas might explain the Ice Ages. The major contributing scientists in establishing this relationship and predicting global warming were Arrhenius and Chamberlin.
However, air pollution is the most dangerous form of pollution that threatens the survival of human beings and the earth. This is due to the reason that living things (humans and animals) depend on air for sustainability. If the air is not clean, then that would immediately terminate the human and animal life.
The sun is at an angle also.
In contrast, the sun is lower in the sun when areas are experiencing winter. This means that a beam of sunlight will have to cover more area which means that the earth does not get as hot. Another
However, the Montreal Protocol holds the promise that this reduction is now stabilizing and may return to pre-1970 levels by the middle of 21st century.
Ozone, O3, is a gas that could be good or bad for humans and the environment,
ty, nitrogen pollution causes "changes in the composition and functioning of [aquatic] ecosystems and contributes to long-term declines in coastal marine fisheries" and biodiversity.
The roots are damaged by acidic rainfall, causing the growth of the plant to be stunted, or
Nonetheless, the major types of pollution include water pollution, air pollution, and soil pollution, among others. These have a detrimental impact on human beings and all living organisms, as well as their
The impacts of global warming have been seen in the changing climatic patterns around the world with the climatic seasons becoming less distinct as they were in the past. According to Good, Gosling, Bernie (2009), the rising sea levels
The gravitational pull will be so strong that anything including light can not get out from it. So, when no light can escape from it, the specific place has to be black in appearance and so not directly visible to
