> This might be a true association but still not explain most of the cases of autism in kids being born today- DDT has been illegal in most countries for 30 years. Not necessarily. The effects could be transgenerational (there's already precedent for that with other substances and executive function disorders, of which ASD is one[0]). Even the rise in autism cases isn't necessarily evidence against this link, because the ability to diagnose people 30+ years ago was dramatically different from our ability to properly diagnose people today.
