We now know from a Princeton study that Superfund sites are causing higher rates of birth defects. We now know that there's no excusing the lack of moral urgency to do something about this environmental crisis. We see Flint, Michigan, for example, and the attention it's gotten, but what most Americans don't seem to realize is that this lead problem is not confined to just Flint. There are over 3,000 jurisdictions that have twice the lead levels in people's blood than Flint does. We're now seeing more people being exposed to the truth about environmental injustice in our country.
