Paper Introduction:
Dangers of Ozone Layer Depletion
The ozone layer, or ozonosphere, is located in the stratosphere surrounding the earth, and is responsible for protecting the life on the planet -- human, plant and animal, including the life in the sea -- from the dangers of overexposure to the ultraviolet light from the sun. The ozone layer essentially changes the ultraviolet rays into a form of radiation which is not harmful. Therefore, "holes" in the ozone layer constitute a danger to all life on earth, which are exposed to the harmful UV rays. What are known as "holes," however, are not truly holes but rather a thinning, to various degrees, in that layer.
The ozone layer depletion is man-made, created by chemicals, particularly aerosols. When the depletion of the ozone layer was discovered in the

The entire text of the paper is shown below. However, the text is somewhat scrambled. We want to give you as much information as we possibly can about our papers and essays, but we cannot give them away for free. In the text below you will find that while disordered, many of the phrases are essentially intact.
