How Nurture Affects Nature

November 15, 2017

Policymakers often debate the merits of programs to change decision-making and behavior, wondering if they have enough bang for the buck. Now there is research showing that the choices people make affect us all the way down to the genetic level, and can even influence the biology of our offspring.

What We Don’t Know Can Hurt Us: Toxic Chemicals, Science, and Policy

In February of this year, President Trump signed an executive order to roll back the clean water rule, which limits corporations’ ability to pollute about 60% of U.S. waterways. The irony is that we know more than ever before about how toxic chemicals adversely affect people, and we can be certain that what we don’t yet know can hurt us. Scientific research on potential chemical contaminants is both
