Is it true that the ozone layer has been destroyed?
assistant
Yes, it is true. The ozone layer is a thin layer of gas in the stratosphere that absorbs UV radiation from the sun. In the 1980s, scientists discovered that the ozone layer was being depleted by chlorine and bromine compounds released into the atmosphere by human activities. This depletion of the ozone layer has led to an increase in UV radiation reaching the earth's surface, which can cause health problems for humans and animals.
