What is the conclusion in here, besides that carbon monoxide could be actually WORSE for human health due to fraudulent research? Maybe we should check in-door air in big cities as it might be worse for us than we think.

Donnay says the HEI study, which was funded by the EPA and the automotive industry, is filled with fraud and needs to be investigated. In the study, human carbon monoxide levels were tested on men who had coronary artery disease.

They found that low levels of carbon monoxide made angina worse during the exercise, and the EPA used it to support its carbon monoxide standard. The study also played a key role in a 2011 review of carbon monoxide regulations. The $2.5 million study was published...

First they, a regulatory agency, are captured by an industry that they were supposed to have been regulating. Then they spend 2.5 million taxpayer dollars to fund a fraudulent study. Two questions: who will regulate the regulators and why am I paying for all this corruption? These so-called environmentalists are too naive to comprehend the real problem. If we point out what is going on to them, they'll say we're against environmentalism and support pollution. The reality is that they are.

Reminder that the global warming (which is not happening) crowd have perverted and co-opted true environmentalism. A healthy nation, by definition, has environmentalist policies, as stewardship of the Earth is the means by which a nation is passed onto its successors.
