I'll give a brief answer, to start.
Whether it's for kids in school or for governments, at a certain point you have to stop producing report cards and start improving the grade.
I do think it's fair to say that the federal government has been mired in process on the issue of pollution over the last few years. I would agree with Dr. Levy that a much more effective, common-sensical measure of success for CEPA would be to determine whether it is decreasing emissions into the air and water of key toxic chemicals. Is it ensuring that levels of toxic chemicals like brominated flame retardants, PFOS, and other things that other industrialized countries are well on their way to banning are decreasing in the bloodstreams of our children? We can measure these things now. Doing so is actually quite cost-effective. These are the kinds of measures that I would suggest are more effective. In fact, the United States, for instance, for many years now has been testing hundreds of people every year for the levels of toxic chemicals in their bloodstreams and in their urine, in order to track progress on pollution reduction.
