Ozone depletion

Ozone depletion is also a very important ecological problem. The ozone layer is thinning. For the last 20-25 years as it was announced by experts it became 2% thinner.

First ozone depletion war found out over Antarctic in 1978. It increased from 5 up to 20 million square kilometers. The international researches show that ozone depletion is still increasing in size. Besides new ozone 'holes' appeared over Europe and the USA.

The ozone layer is being damaged by gases which are called CFCs. Unfortunately emissions of these gases especially Freon grow every year because they are used in refrigerators, air conditioners, plastic foam and other things. Spaceships and planes also influence the ozone layer.

One of the effects of the ozone depletion may be genetic mutation. According to the papers of the ecological conference the number of children and adults with diseases of blood and skin is growing.

Different countries began to unite their efforts to stop the ozone layer from disappearing and we care about the environment and we are concerned about ozone depletion too.
