Recently, Dr. Tracy Ann Becerra and colleagues from the Fielding School of Public Health at UCLA reported that air pollution is directly correlated with autism. That is, the more air pollution the more autism. A far as theories, the discussion in the paper showed the UCLA group did not think out of the box; all they could come up with was a discussion that pollutants in air are directly causing autism. If air pollution was causing the epidemic of autism, then that epidemic should have peaked in the 1950s, when air pollution in the USA was at its worst. Instead, it has yet to peak.
