Air. We all breathe it, every minute of every day. But in addition to the oxygen your body needs what else are you pulling into your lungs everyday? The U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, National Parks Service, tribal, state, and local agencies have developed the AIRNow Web site to provide the public with easy access to national air quality information. From this website you can check out what is in the air you are breathing right now! You can also get the latest information on the ozone layer, UV radiation and much more.
