Ozone layer recovering at 1-3% per decade: UN
The Earth's ozone layer is recovering at a rate of 1-3% since 2000, a UN report has revealed. The ozone layer was damaged by chlorofluorocarbons and other ozone-depleting substances. The report attributed the recovery to the 1987 Montreal Protocol, a global pact that aims to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances.
