The ozone layer is an invisible layer in the stratosphere. It has always been needed by all life on earth, as it absorbs the ultra violet radiation (UV) from the sun. Recently a large hole has appeared in the ozone layer over the Antarctica, and a similar but smaller hole has been found over the Arctic. The problem with the ozone holes was first noticed in the 1970’s by a research group from the British …showed first 75 words of 356 total…

Scientists feel that the ozone layer should recover if the substances that destroy it are eliminated. However, long-term predictions are uncertain because the processes of ozone depletion are not all understood. As well, global warming and the exhaust from high-flying aircrafts may significantly affect the recovery of the ozone layer.
