News on the ozone

For those who are wondering what the news on the ozone is, and what we can do about it, here it is. It's not all bad. Since the CFC (chlorofluorocarbon) ban, scientists at the National Oceanic and Atmospheric Administration. are saying. (CFC's were prevalent in aerosol sprays.) According to them, with continued vigilence, the ozone layer should continue to repair itself. Although it has been overlooked lately in favor of global warming, ozone gas (O3) contributes more to global warming than was previously believed.

How can you help? By disposing of older (pre-1994) refrigerators and air conditioners properly, to avoid releasing CFC's into the air. Switching from aerosols to pump sprays is an easy step. In addition, some asthma inhalers use CFC's. If you use one, check with your physician. Another ozone depletor is the pesticide methyl bromide; here's one more reason to support organic farming.

Items like hair sprays, paints, and foam plastic products are regulated by the EPA's Clean Air Act, updated in 1990. You can also visit the EPA's home page to check your state's air quality and to find other resources.
