INTERNATIONAL: A new study published in the journal Nature has found that the Earth's ozone layer is recovering at a faster rate than previously expected. The ozone layer is a layer of gas in the stratosphere that protects us from harmful ultraviolet radiation from the sun. It was depleted in the late 20th century due to the release of ozone-depleting substances (ODSs) such as chlorofluorocarbons (CFCs).

The study found that the ozone layer is expected to fully recover by the middle of the 21st century. This is good news for human health and the environment. The ozone layer protects us from skin cancer, cataracts, and other health problems. It also protects plants and animals from harmful UV radiation.

The study's findings are a testament to the success of the Montreal Protocol, an international treaty that was signed in 1987 to phase out the production and use of ODSs. The Montreal Protocol has been credited with preventing millions of cases of skin cancer and saving millions of lives.

This good news story is a reminder that we can make a difference in protecting our planet and our health. By working together, we can overcome challenges such as climate change and ozone depletion.
