Sadly, simply saying something is 'bad for you,' or causes problems for human health, is not satisfactory for government-implemented policy. Years and volumes of data indicating a problem are needed to combat the use of whatever it is (i.e. industrial use of certain chemicals, certain pesticides, etc). This usually results in going down rabbit holes to prove inane points of HOW exactly this thing is bad for you. Research funds and man-hours are wasted on experiments necessary to find the smallest amount of a chemical that will not cause adverse effects ("Acceptable Daily Intake" of certain food additives, supplements, or even pesticide residues on foods, for example). Instead of eliminating the contaminant, industry waits for more time to pass with these studies and new policies to pass before they're ever expected to change.
I think some of the most important things I've learned in this program are about the politics surrounding the policy and decision-making towards anything public- or environmental-health related. It's quite amazing how little priority either of those two things get in this (and most) country(-ies). I love learning, but many times,the more I know, the angrier/sadder/more frustrated I become. I find myself envying the oblivious and ignorant, which is an interesting conclusion to come to when striving for 'higher education.'
