Have you ever wondered where ADHD in children comes from?

This is currently a we don't know shit issue. There really is no evidence that perchlorate is a problem. There are a bazillion other contaminants out there that are clearly much bigger problems. Try radon or lead, which are far more damaging than the latest contaminant du jour, but are ignored by the public because there's no single polluter to pin the blame on, and in the case of radon all we can blame is mother earth. Although the right wingers are wrong on so many anti-environmental issues, in the case of many pollutants, the left wing is also full of shit. Perchlorate MIGHT be a big environmental problem but the jury hasn't even started deliberating.

Oh, and you "ADHD isn't important" people...this is a very real problem, though the importance has been diluted by overdiagnosis. So, unless you actually know something, STFU.
