Quote:Except that chemical interactions would (I assume, not being a chemist myself) be one of the easier things to test for: Put chemical A and chemical B in close proximity to each other, under the same conditions as are up in the stratosphere, and document what happens.
It is realistically impossible to prove one way or the other, as we would have to be comparing the size of the holes without mans interference with the size of the holes in the Ozone Layer after mans interference. Never mind the extent of the damage being calculated we dont have this pre-interference data or data on what it would be like without man influencing the system at all.
Various scientists have done this, and come up with the following results:
EPA List of Ozone Depleting Substances - Class 1
EPA List of Ozone Depleting Substances - Class 2
I'm puzzled why some people seem to think that just because humans aren't the sole cause of ozone depletion (or global warming, as per the other thread), that we should just do nothing about it.
