Hi Sam,

As the story notes, this is just one part of a three-part series. The final section, which discusses some things scientists and manufacturers are doing to address these issues, will be out at ensia.com either tomorrow or early next week and will be posted to Medium shortly after.

That said, this, like many issues we face, is a complicated issue and therefore solutions are complex as well. Hopefully you find something helpful in the last part of the reporting series.

Thanks for reading,

David
