CFC's were banned in 1978 from use in most aerosols. Only a few product types needing to use CFC propellents were allowed to continue using CFC's....an example is inhalers.

For the same reason they seem to think the ozone hole is causing global warming. Because they are ignorant!

Sorry--but CFC's are indeed the cause of ozonne depletion. You are forgetting two things. First, not all CFC production worldwide stopped right away.

Second--and more important, CFCs once in the atmosphere take decades to break down--up to a century. In the meantime, they act as a catalyst. Chemically, that means thechemical reaction that breaks down ozone doesn't "use up" the CFC molecules--they stick around continuing to break down more ozone molecules. we do knnow that CFC concentrations are declining in the atmospher--slowly. And although there have been some locally intense areas of ozone depletion in the last year or two (you may have read about them) the overall levels of ozone are beginning to recover--but also slowly.

BTW--try getting your science from sites like nasa.gov, instead of the conspiracy websites. Otherwise, you just make yourself look foolish. :)

i think of you're flawed. i've got self assurance CFC aerosols have been banned by utilising international treaty years in the past. as properly which, they have been meant to have broken down the O-zone, that may not be concerning international warming, yet is approximately destroying the layer of the ambience that protects us against cosmic radiation.

Propane is used though. All that energy to produce a fuel and all it does is help propel deoderant through the air. What a waste.
