Hypothetical solutions to address this issue are listed below. Match each solution to its correct category of Upstream Solution or Downstream Solution.
Pass legislation (policy) to ban entire chemical classes of compounds that have any evidence of harmful health effects. Taking a "Class Approach" may help avoid regrettable substitutions.
[ Choose ] Downstream Solution or Upstream Solution
Individuals who work in Dupont or Chemours factories should request appropriate Personal Protective Equipment (PPE) to prevent exposure to workplace chemicals.
[ Choose ] Downstream Solution or Upstream Solution
Pass legislation (policy) to require adequate testing of chemicals used by Dupont, Chemours and other corporations before new chemicals are released onto the market or added to consumer products
[ Choose ] Downstream Solution or Upstream Solution
Consumers can boycott (refrain from buying) products made by Dupont and Chemours, and more generally they can avoid non-stick and waterproof consumer products unless they are absolutely necessary.
[ Choose ] Downstream Solution or Upstream Solution
