The ozone layer is a fragile shield of gas, which protects the planet from the rays of the Sun. Life on Earth would not be possible without sunlight, but the energy of the Sun would be too much strong for life without the ozone layer. Ozone acts as a shield against ultraviolet radiations. Back in the late 1970 scientists discovered that humanity was creating a hole in the protective layer and raised the alarm.

On 16. September, we celebrate the World Ozone Day, with the purpose to spread awareness about the ozone layer’s depletion, as well as the search for solutions in order to preserve it. In 2020, we celebrate 35 years of global ozone protection. Thanks to the Montreal Protocol (which dates back at 16. September 1987) the ozone layer is healing and expected to return to pre-1980 values by mid-century. The World Ozone Day celebrates this achievement.
