I once held a universal refrigeration certification from the feds. The CFC's from refrigerants were supposed to take 40 years, to punch giant holes in the ozone layer; (maybe a 32nd of an inch thick). Over New Zealand, it was said that sheep would go blind from ultra violet light, plant life would be destroyed and so fourth. As a result,the industry changed many refrigerant to isotropic blends (which causes problems when you get a leaky system), changed the tools, couplings ect... yet nothing happened! I also learned that dry cleaners were exempt from spraying CFC's directly onto suites for cleaning, hmm that sounds fishy too...
These type of inconsistencies tells me it is all about money and politics; to include any type of "fossil fuels" which could be produced right here in the USA, and produce more energy than the 1901 oil boom! Green energy is wonderful and all; but no reason has been proven to exists which should hinder or stop production of fossil fuels: drilling, mining, or fracking practices, with modern technology and filtration seems to be safe.
The exceptions have been halted, but the media seems to still generate propaganda on the subject. For me this is all about, promoting one political party over another, and their energy industry buddies, using voodoo science, while attempting to control money, business, and to keep hold of political power, instead of everyone working together for the common good like during WWII.
That's my opinion about what is actually going on nowadays, yet with so much info overload today, it seems you can't prove anything to anyone unwilling to listen.
