Stratospheric ozone, otherwise known as the ozone layer, is a layer of gas (O3) that partially shields the earth from the sun’s ultraviolet (UV) radiation. In the latter-half of the 20th century, use of chlorofluorocarbons (CFCs) punched a hole in the ozone layer up to 11.4 million square miles in size and thinned it elsewhere. The increased UV rays have lead to higher rates of skin cancer and eye problems. The good news is that bans on CFCs have significantly slowed the growth of the ozone hole.By avoiding products and practices that damage the ozone layer and by lobbying for more action from government and industries, you can help to close the hole by the end of this century.

Check your fire extinguishers to find active ingredients. If “halon” or “halogenated hydrocarbon” is the main ingredient, find a hazardous waste center at which to recycle it or call your local fire department for instructions on how to dispose of it. Replace it with a model without this harmful ozone-depleting chemical.

Don’t buy aerosol products with chlorofluorocarbons (CFC). Although CFCs have been banned or reduced in many applications, the only way to be sure is to check the label on all your hairsprays, deodorants and household chemicals. Opt for pump spray products over pressurized cans, to further reduce your chance of buying CFCs.

Dispose of pre-1995 refrigerators, freezers, and air conditioning units properly. These devices use chlorofluorocarbons to function, so leaks release the chemical into the atmosphere.

Call your local utility company to see if there is a bounty program in your area that your appliance qualifies for.[4]

If not, contact your municipal department of public works to ask how to dispose of refrigerated appliances in your neighborhood.

1. dont use transport which emits powerful gases which are harmful for our earth such as carbon monoxide found in gas emitted by our cars instead use bicycles or walk this way we can stay fit and healthy.

2. dont buy aerosol products with cholorofluorocarbons in them (CFCs)

3. buy air conditioning and refridgerating equipments that dont use HCFCs are refrigrants.

4. Avoid the use of fire extinguishers with halogenated hidrocarbon, a substance being very aggressive to the ozone layer.
