The ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometres (12 to 19 mi) above Earth. It protects the earth from harmful ultraviolet radiation. Scientist in the 1970’s discovered that the layer was thinning as a result of the release of CFC’s which resulted in the development of ozone hole.
