Ozone Depletion

As far back as human history goes, scientists today have discovered the depletion of the ozone layer and have studied how it is caused by human actions and inventions that affect our environment and style of living. As the cause of this, many changes have been taking place during the past twenty years or so that humans have and still are concerned of, as they search for new ideas to alleviate this problem. The three main causes of the ozone depletion are the use of CFC's, the increment of carbon monoxide and dioxide and the use of greenhouse gases, thus, permitting penetration of UVB, ultraviolet light type B, into the ozone layer, calamitous behaviors and reactions in living species, and the drastic amendment in weather.
During the nineteenth century, several discoveries and inventions took place, like the invention of the (CFCs), chlorofluorocarbons, that were thought to be helpful to human daily activities, which is indeed true, and to make life easier. These chemicals were believed to be miracle substances; they were thought to be low in toxics, nonflammable, inexpensive and stable to produce equipments and production such as, refrigerants, solvents, foam blowing agents, and other smaller applications.(1) These substances fused to release chlorine or bromine. Though, these chemicals are used for a certain amount of time, because they break down subsequently and consequently they damage the protective ozone layer which protects the earth from the Ultraviolet light released by the sun. If the ozone layer is depleting, then the UVB rays will be more accessible to earth after it has trespassed the atmosphere's layers. Afterward, it will affect the outer layers of the skin, aging the skin, and will be responsible for causing sunburn, hence, the development of skin cancer. Even though the UVB lights are naturally dispersed by the sun, they are composed by smaller wavelengths that are stronger and more deeply penetrable in al…
