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.
So, instead, California continues to mostly build single family housing sprawl into natural habitats.
A clear example of environmental regulation hurting the environment and the climate. And of course the affordability of housing.
One of the biggest problems today is that urban planning has basically evaporated. Local and state governments don't plan towns anymore. Things are left to developers who have no other concern than to run a street off a major road and plop a few houses down, sell, and move on to the next project. No thought is given to traffic or public services or walkability or public transportation. No care is given to integration with existing urban structures. Instead of mixed-use zoning or building houses around a common public space, which are historically the more common and sensible form of urban planning, we end up with car-dependent suburban dead zones, suburban sprawl.
This should be receiving more attention from environmentalists, as urban planning is intimately related to environmental issues.
And in many cases, single family homes are perfectly fine. You don't build skyscrapers in the Catskills. So they're not the issue. The issue is how they're arranged. Look at how old towns, even in the US, were or are constituted (at least those that have remained unscathed by Robert Moses-style mutilation). Plenty of single family homes arranged around a discernible town center. Walkable. The density consists of building around a town center instead of building willy-nilly along a road, because some strip of farmland has come up for sale. (This has the incidental defect of building on fertile land, now lost permanently to residential space.)
