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.
The worst environmental crisis in human history is going largely unchecked. I find it hard to take seriously any argument that environmental regulation has gone too far as opposed to not nearly far enough.
If there's a specific regulation that can be shown to be doing more harm than good I'm cool with revisiting anything, but the common sense wisdom around environmental regulation has been corrupted by corporate public relations campaigns.
In Massachusetts you can't clear shoreline. Specifically, if you buy waterfront property on a pond / lake, you can't clear the shoreline to make a beach in your backyard. You can only use what used to be there before the law was passed. There's even restrictions on building close to shorelines, so if you want to build, you need to find an existing building and renovate.
Now, I'm not a wetland expert, so maybe someone will chime in and tell me why every inch of freshwater shoreline must be undisturbed. But I like freshwater swimming and suspect that we can allocate some space for human recreation.
