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.
In general the pressure against regulation comes from narrow winners (oil industry for instance) whereas the pressure for regulations generally comes from people focused on the greater good (even if they are misled by other narrow winners, for instance compliance firms).
That’s a very broad statement. I expect there are many cases where that is not true.
There’s no copper sulfate in canned green beans or borax in beef. Those seem all around good.
Let’s agree that impacts of regulations are nuanced, and not try to condense it down to something overly simplistic like, “regulations hurt poor people”.
