When did we really start damaging the ozone layer?

    Freon, also known as CFC’s, acts as the most destructive compound to ozone.  Freon was invented in 1928 by Thomas Midgley Jr. and Charles Kettering as a safer replacement for refrigerants.  Later, in the 1950’s when CFCs became a critical component in aerosols, ozone depletion became rampant.  The fluoride and bromine released from the aerosol compounds persists in the stratosphere long enough to execute its natural tendency to break down ozone molecules.  

    Further studies revealed these findings which led to the outlaw of CFCs in 1978.  Though CFCs are illegal in the United States, many developing countries still use CFC based aerosols today.  The era of ozone depletion began in earnest in the 1950’s and continues on today.
