　　Radiation from the Sun continuously breaks two-atom oxygen molecules into single atoms. Some of these link up with ordinary oxygen molecules and form ozone. Some rejoin other free singles and revert to stable molecules. This Sun-energy process, if left undisturbed, maintains a fairly constant supply of ozone above the Earth’s surface. The ozone layer begins about eight miles up and is distributed thinly to about thirty miles up. This lofty umbrella of ozone shields the Earth from much of the Sun’

　　Some scientists believe that relatively small amount of synthetic chemicals, such as spray-can fluorocarbon or jet exhaust, reach the upper limits of the atmosphere and break down the three-atom ozone molecules. It is also believed that just one atom of the spray-can or get pollutant can affect vast numbers of ozone molecules. Weather research satellites have observed the ozone shield in great detail, but their data have neither put to rest the “doomsday theories” nor incited a global campaign to stop destroying the Earth’
