Study: Ozone finally showing signs of recovery
from Nature World News
Finally, the world can rejoice over some good news about the environment. The Earth's protective ozone layer, which shields us from harmful ultraviolet rays, is showing signs of recovery, according to a new United Nations report. This atmospheric layer is slowly rebuilding itself after years of dangerous depletion, which left a giant hole over Antarctica. But this gap has now stopped expanding, and experts are crediting the ozone's recovery to the phasing out of harmful man-made chemicals used in refrigerators, air conditioners and aerosol cans.
