The internet is hear now, I don't even want to search out this as a conspiracy theory, I don't have the energy or the time to care. I am fascinated by changes in science. Like how no one knew how fermentation existed, and that the word yeast, fermentation and leaven all have the same root meanings. Louis Pasteur came along and went to France to study the grapes and vines to find how yeast was produced. And how his discoveries helped lead us out of dark age of zymotic disease theory. And how doctors at one time didn't wash their hands, yet deny today that their practice was once monstrous and bestial, yet chiropractors are the new "evil". The thread of logic and evidence is incredibly fascinating. And so I had similar questions arise with the ozone layer. Some things didn't seem to add up, so I asked about them here.
