A United Nations study says that the Ozone layer that protects the earth from the dangerous cancer-causing ultraviolet rays is showing signs of thickening after years of depletion.

According to the UN report, the Ozone hole will take a decade before it starts contracting.
Scientists said that the recovery came following political determination to reduce the man-made CFC gases from the environment that deplete Ozone layer, reported the BBC.
World Meteorological Organization's Secretary-General Michel Jarraud said that global action towards protecting the Ozone layer is a major success story in the field of environment.
The UN study was published by World Meteorological Organization (WMO) and the UN Environment Programme (UNEP) researchers.
