             acle is evident: Such is the structure of the atmosphere that it only per-
             mits light within the range necessary for life to enter, and all other
             harmful rays are reflected back. The atmospheric layer responsible for
             this filtering, of such vital importance for life, is the ozone layer, com-
             posed of oxygen molecules with the chemical formula O3. From among

             all the other 1025 wavelengths, the ozone layer absorbs 97-99 percent of
             the sun’s high frequency ultraviolet light which is potentially damag-
             ing to life on Earth and admits only light in the visible that are essential
