In my opinion it is obvious and should be uncontroversial that some environmental regulations work and are great and should if anything be reinforced, while other environmental regulations do more harm than good and need to be reigned in or eliminated.

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.

Lead is a textbook example of a good regulation. It’s something where the industry was doing something very harmful-aerosolizing lead and pumping it into the air—which had quite small economic benefits and was relatively easily replaced.

Some regulation achieves this kind of improvement, and we’re probably under regulated in those areas. Particulate matter, for example, is extremely harmful. But many regulations do not have such clear cut costs and benefits.

Can you tell more about particulate matter ? You mean small particles in the air right, so air pollution right ?

Particulate matter is relatively large particles, so far as air pollution goes. Think things like soot or smoke, rather than specific chemicals. Burning wood and coal produces far more particulates than, say, natural gas or gasoline-gas.

They're not necessarily large, and the worst for humans is small particulate which gets into the bloodstream through lungs, PM2.5.

Breathing in unhealthy levels of PM2.5 can increase the risk of health problems like heart disease, asthma, and low birth weight. Unhealthy levels can also reduce visibility and cause the air to appear hazy.

Outdoor sources include vehicle exhaust, burning wood, gas and other fuels, and fires. Particle pollution can also travel long distances from its source; for example from wildfires hundreds of miles away. Outdoor particle pollution levels are more likely to be higher on days with little or no wind or air mixing.
