The problem called ozone holes being long ago, but this not lose its actual. Today all know about harm from sunbathe long time and possibility get ill skin cancer. But this becomes habit and people least heed on the depletion of the ozone layer. It is vain; because skin cancer is one of the many consequences of decompose ozone layer.

The fact is ozone layer is shield, which protects the earth from extreme heat radiated by the sun. But during many years and at influence of harmful factors the ozone layer deplete and in this appear so-called “holes”, which pass sun radiation to earth. It began to represent threat of a life on a planet. Differently when we destroy ozone layer we destroy our life.

The ozone deplete is lot of, basically it is emission of industrial enterprises, which incorporate CFC. CFC or chlorofluorocarbons is one of the most dangerous groups of ozone depletes. Because chlorine, which contain in CFCs, speeds up the breakdown of ozone molecules, thus leading to a depletion of the ozone layer. Moreover some CFCs are at least 10000 times more powerful then carbon dioxide in trapping heat in the atmosphere, thus contributing to the “Greenhouse effect”. While a lot of ozone deplete it is forbidden to use today, they have been used for many years as propellants in aerosols, in the production of some foam packaging for food and as coolants, in refrigerators and thus already considerably affected on the deplete of ozone layer.

The most terrible in a deplete of an ozone and in a consequence formation ozone holes is that this process is irreversible. But to stop it in our forces. Therefore the governments of all countries need to reflect seriously on use of safe substances for an environment, development of the without waste industry and recycling.
