I'm old enough to remember when CFC and non-CFC hairsprays were both available, and recall the public discussion over whether you should buy one or the other.

I'm old enough to remember when CFC and non-CFC hairsprays were both available, and recall the public discussion over whether you should buy one or the other. Regardless, even though the edict eventually came from on high to stop using CFCs, it was the individual use of them that was ultimately responsible for harm. Punishing oil companies won't make a lick of difference if it doesn't result in changes to our collective, individual behaviour. Like how we stopped using CFC-laiden hairsprays, we're going to have to stop commuting by car, ICE or EV, and stop buying products from overseas, and stop flying. There is no technological panacea that will allow us to continue to live our lives as we do now.
