Depletion in Our Ozone Layer

It's no news that the weather has been so bad, really really bad of late. The severe heat is worth shedding tears over. And for good reason. We're experiencing severe depletion in our ozone layer. Ozone layer depletion is the gradual thinning of the earth’s ozone layer present in the upper atmosphere. Ozone depletion also consists of a much larger springtime decrease in stratospheric ozone around Earth's polar regions, which is referred to as the ozone hole. The depletion experienced by the earth's ozone layer caused by manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons..etc have lead to increase the rate of skin cancer, eye cataracts, and genetic and immune system damage.It may also cause leukemia and breast cancer. UV exposure to human eye damages cornea and lens leading to photokeratitis, and/or even blindness. Emphysema, bronchitis, asthma and even obstruction of lungs may be caused on exposure of UV light to human beings. Excess of UV light exposure causes DNA breakage, inhibition and alteration of DNA replication and premature ageing in humans. Much milder consequences are the heat stroke, heat rashes, excessive sweating..etc.
