There is not just one particular cause for the ozone’s depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. As the ozone layer is getting thinner and thinner more and more harmful UV rays are passing into our atmosphere. These rays cause cancer, cataracts, and lowered immunity to diseases. In recent years, scientists have sounded alarms internationally about the depletion of the ozone layer, citing chemical pollution as the major cause.Ozone is a natural trace component of the atmosphere. It is created continuously through the action of sunlight and oxygen in the upper atmosphere. For millions of years ozone has been protecting the earth by absorbing ultraviolet or poisonous radiation from the sun. This poisoning of the Earth’s ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth.
