Each year we mark national Autism Awareness Month with an update on how many children officials say are now on the autism spectrum. We highlight the latest science linking prenatal pesticide exposure to increased risk. And we make an urgent pitch to shift from awareness to prevention.
Well, once again the numbers are up. CDC reports that 1 in 68 children are now on the autism spectrum, up from 1 in 88 in 2008 and 1 in 150 "way back" in 2002. And once again, new science links certain chemical exposures to derailed fetal brain development — with an ever clearer understanding of how the damage is done. The good news? When it comes to talking prevention, there's been real progress.
