It takes another 60 years, the ozone layer can fully recover . Estimates of the US Aerospace Agency (NASA).

Protecting the ozone layer

Although the ozone layer defends life on Earth is shrinking, but it still takes another 60 years for the ozone layer to fully recover, returning as it was in 1980.

The measurements of the US Aeronautics Agency (NASA) revealed that the hole in the ozone layer between September and October 2005 was 24.3 million km2, narrowed considerably compared to the area of ​​26. , 4 million square kilometers in 1998.

However, the rate of narrowing the ozone layer has been slowed.

The reason is that the amount of CFC gas that destroys this Earth protection layer is still discharged into the atmosphere in larger quantities than scientists have forecast.

Of the total CFC emissions, developed countries' CFCs still account for more than 50%, although these countries have been banned from using CFC since 1987.
