Turning "environmental regulation" into a unified bloc that must be either supported or opposed in totality is a manipulative political maneuver and it should be forcefully rejected.
Regulations are not people, and they don't have rights. It is fair and reasonable to demand that environmental regulation justify its existence with hard, scientifically verifiable data or else get chopped. Clearly, banning leaded gasoline has that kind of justification, and therefore I'm strongly in favor of maintaining that ban and extending it wherever it isn't in place yet. The same reasonable standard should be applied to other regulations across the board.
This was a case of zealotry and overregulation egged on by puritanical ideologs without full consideration of the consequences.
We correctly banned fluorocarbons as refrigerants in systems where they would not be properly recycled, such as domestic refrigerators, air-conditioning systems incuding those in vehicles, and like. This made for good regulation, and it made sense.
The volume of CFCs with other specislist applications was miniscule by comparison, and for most of these recovery, capture and recycle systems along with protocols for use could have been implemented.
Instead, we stupidy put an outright ban on just about every CFC in sight, many of which have no direct equivalents that are anywhere near as effective as CFCs, and many are dangerous and inflammable and form explosive mixtures with air.
Right, in one fell swoop we banned many of the most useful chemicals ever invented. Little wonder these's now a backlash to overregulation. If Montreal were to be repeated today the zealots would have to take more of a backseat.
