Do hydrofluorocarbons destroy the ozone?
No, they do not. They are an alternate to CFC's.
What is HCF in the ozone layer?
HCF are hydrofluorocarbons. They are the alternates to the CFC's.
How are hydrofluorocarbons bad?
- contribution to the greenhouse effect - contribution to the depletion of the ozone layer - toxicity
Why are CFC bad for the environment?
The stratospheric ozone layer makes it possible for life to exist by shielding the earth from harmful ultraviolet (UV-B) rays generated from the sun. There is a substantial amount of scientific evidence that suggests man-made compounds such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs) and halons destroy ozone in the upper atmosphere (stratosphere). Decreased concentration of stratospheric ozone allows increased levels of UV-B rays to reach the earth's surface.
What are HCFCs and what is their effect on the ozone hole and on global warming?
Hydrochlorofluorocarbons (HCFCs or Freon) are the replacement for chlorofluorocarbons (CFCs). The chlorine released from CFCs is very destructive of the ozone layer. HCFCs are less stable than CFCs and much of this gas breaks up before it reaches the lower stratosphere where the ozone layer is. However, some chlorine from HCFCs is still reaching and damaging the ozone layer. Other alternatives, hydrofluorocarbons (HFCs), which have no chlorine have been developed instead. These have no effect on the ozone layer. Unfortunately, one of the replacements, HFC-134a (aka R-134a), for example, used in automobile air conditioning units, is 1430 more powerful as a greenhouse gas than carbon dioxide (CO2).

How do you avoid the thinning of ozone layer?
Stop pumping hydrofluorocarbons (HFCs) into the atmosphere.See "What can we do to protect the ozone layer?" in the "Related questions" section below.
