When scientists focus on these contributions to the Gulf Coast's pollution problem and ignore the petroleum industry, cattle industry, repaving industry (melted tar, road dust, construction equipment, etc), trucking industry, port shipping industry, biological decay (vegetation, crops, forests), etc. it shows that they'd rather not address issues.
This same kind of misdirection got the EPA to lower our speed limits (the legislature didn't do it) from 70MPH to 55MPH (even though they knew that it wouldn't significantly change pollution levels).
"Meat cooking is more important than wood burning, but it's less important than diesel," Fraser said. "These are trace levels. They are very low concentrations."
It doesn't sound like the environmental engineer is trying to ban them or anything like that.
