It was merely a coincidence that DuPont’s patents on Freon and all it’s derivations were running out in the 90’s. Absolutely coincidence that they just happened to have a ‘new’ and more expensive chemical, freshly patented, to ‘replace’ those old ‘dangerous’ chemicals. Amazing coincidence........................
That old "ozone hole" really came in handy.
Forget the fact that we really don't know if the "ozone hole" was always there. That doesn't matter. The important thing is we have something to demagogue so we can use it to make money.
