EnviroMENTALism is like any other movement or group that fights for relevancy after its usefulness has passed. We've reduced particulate and NOX emissions from diesel by 95% or more since 1990. We've reduced NOX and other hydrocarbon emissions from gas engines by more than 90%. The job is DONE!!! The wild and baseless idea that CO2 is a pollutant only came about AFTER we solved the pollution problem! EnvironMENTALism has now become a scam as it fights for its own survival in the face of obsolescence.
