Ozone is a trace gas. Although the concentration of trace gases in the atmosphere may be only a few parts in a million, they have a profound effect on the environment by absorbing radiation in important regions of the spectrum. Ozone absorbs harmful radiation from incoming sun Wrapped around our Earth is the atmosphere, which has evolved over the course of billions of years. Without this protective blanket, life as we know it would be impossible. The thickness of the atmosphere is in proportion to the thickness of the skin on an apple and is more fragile than we would like to imagine. Over the past century, scir entists have begun to realize FACT: that human beings are playA one loss in ing a significant role in modicomthe atmosphere's fying ozone will result in a position.

As scientists have identified the ozone hole, the greenhouse effect, and acid rain, we have become more aware of the extent of the large-scal- e damage people have done to the earth. "It's a lot different here than in Oregon. Back home, people cared about the environment," said sophomore Mike Sherwood who is from Coos Bay, Oregon, but now attending Dixie. For the first time, nations of the world have become conscious of the need to identify and reduce these common threats. In New Zealand, local government legislation has been introduced on pollutants and the government has signed an international agreement to protect the ozone layer. The amount of ozone above a particular location can change from day to night, with the season, and with the passage of weather frontal systems. This makes it difficult to decide how much of ozone depletion is due to human interference.

Be Fooled by the Winter Sun Sun News Sevices (NAPS)- - Consider this: The strength of UV rays at Vail's summit in January were 50 percent stronger than those on a New York beach in June (SKI, November 1997) Although we are continually bombarded with information about harmful UV rays, we often mistakenly correlate that danger with hot temperatures and clear blue skies. Don't let those cold winter days lull you into a false sense of security, however. In fact winter sun can be more damaging to the eye because shiny surfaces such as snow and wet concrete can reflect additional sunlight, up to 85 percent more, causing twice or, even, three times the normal amount of UV Action, (Ozone exposure.
