  • Fps increases

    Fps increases
    “...use of CFCs increases rapidly...”
  • Study on the Ozone

    Study on the Ozone

  • The Sprays are destroying the Ozone

    Assessment Panels recommend that more substances
    (HCFCs, methyl bromide) are controlled and that the phase out
    of CFCs is advanced.”
  • Governments help all around

    Governments help all around
    “In 1987, 46 governments agree to a fifty per cent cut in the
    production and consumption of CFCs by the year 2000; a freeze
    in production and consumption of halons by 1992; further
    controls linked to assessments by experts.”
  • Global Environment does a STRIKE!

    “Some countries, the Russian Federation and others, report an
    inability to phase out CFCs by 1996 due to their internal problems.
    The Global Environment Facility (GEF) offers to help them.
    Developing countries agree to phase out methyl bromide by 2010.”
  • FCF's Stop

    FCF's Stop
    CFC's are taken out of cleaning supplies because they are killing the environment.
  • The CFC's are back

    The CFC's are back
    They brought back CFC's and thought that no one would notice them.
  • Make a better environment

    There are a lot of sprays with CFC's and those are not good types of things even if it cleans or makes you look better I wouldn't use them.
  • The Ozone is the shield

    The Ozone is the shield
    “The ozone layer absorbs most of the harmful
    ultraviolet-B (UV-B) radiation from the sun.”
