- CS~The Ozone Hole
- CFCs are synthetic compounds that were developed in 1920s as refrigerants. Are essentially non toxic and non-reactive = good for fridges and cooling equipment
- meant that affordable fridges were available =better food, vaccine and medicine storage = improved human health and wellbeing
- CFCs also used in aerosol propellants ~ allowed people to have beehive hairstyles etc
- this could have unforeseen consequences eg health effects of breathing in vasts amounts of hairspray
- and graffiti spread
- by early 1970s people grew concerned about the depletion of the stratospheric ozone above Antarctica from CFCs
- The USA banned sprays in 1976
- The Montreal Protocol 1987 - stopped use of CFCs and reduced ozone depletion (the most successful protocol)
- under full compliance with the protocol, the ozone layer is expected to recover to 1980 benchmark levels by 2050
- ozone hole does not appear to be growing anymore
