/^t/First of all, we should deal with it on the individual level. Having known that major CFC (chlorofluorocarbons) offenders are aerosol sprays, refrigeration, vehicle air conditioning and cleaning agents, we can take a few wise decisions. The most obvious is to stop using aerosols using freon. There are many deodorants with the sign "ozone friendly" available in the shops. It is up to us. It is the same story with buying a refrigerator. We must forget about refrigerators containing CFC-11 and CFC-12, even if they are cheaper. It is simply not worthwhile, since the smaller the prize, the bigger the ozone hole (more or less). Another ingenious decision would be to stop using cars in favour of public transport. Recent research shows, however, that this one occurs to be too drastic to be taken. The only thing that can be done about it is then, at least, using catalizators and the petrol of lead-free variety. One more thing that can be done individually is to buy cleaning agents that are biodegradable.
