� Drawing on the readings and other literature, identify some of the emerging issues in this area

literature beyond what we have read in class.
� What changes to practice are needed to make significant reductions to the exposure to this
negative externality or mitigate the impacts of exposure?
� What barriers exist to accomplishing these changes (more research, political will, lack of public

� Speculate, based upon the evidence in the literature, the state of this issue in 10 years. How
might one�s responses to these issues change if writing this issue in a decade? Why?
