Needless to say, this means producing ozone friendly sprays and refrigerators.

They have an additional task, therefore, to establish systems for recycling CFCs from discarded refrigerators and automobile air conditioners. Such systems for the first time appeared in Germany, and they are been worked on in Sweden, Switzerland and Netherlands. Another source of ozone losses are power plants. The logical conclusion then is that it would be better for humans to turn to alternative sources of energy like solar, wind or water energy. Such attempts, of course, present a problem, since energy supply depends not only on available resources, but on economics and politics. Nevertheless, one should never give up so easily. It is also essential, on the national level, to make young people aware of the tragic situation they may occur in unless they switch themselves to the ecological way of life.
