What is the effect that CFCs have on the environment?

I'm not sure about the environment, but fluorocarbons have chlorofluorocarbons (CFC's) in them. Those CFC's destroy the ozone layer, which also destroys the air molecules in the ozone layer.

uhmm-hum. .

I suspect that because the Freon 12 patent expired allowing any company to produce that same product at less than $1 per pound can, that once the R34 Patent expires, the same scare will be used about R34 and yet another replacement will be "needed" to maintain the profits for the original manufacturer.

Fluorocarbons do not destroy themselves in the ozone layer which results in one molecule of CFC could help destroy a lot of ozone molecules. In a little more detail, the process of accelerated ozone depletion begins when chloro-fluoro-carbons [CFCs] and other ozone-depleting substances leak out into the atmosphere. Winds quickly distribute the gases evenly throughout the lower atmosphere. CFCs are extremely stable, and they do not dissolve in rain, so they stay in the atmosphere and some of them gradually gain height. After a period of several years, CFC molecules reach the stratosphere, about 10 kilometers above the Earth's surface, where the ozone layer is.One chlorine atom can destroy up to 100,000 ozone molecules before it finally falls out of the stratosphere. Strong ultra-violet light breaks up the CFC molecules. Which results in CFC's releasing chlorine atoms, resulting in speeding up the natural decreasing process because ozone is naturally increasing and decreasing in density.
