This week on Green Street, Patti and Doug talk about a proposed new law in Louisiana prohibiting people living in Cancer Alley from participating in “citizen science" by collecting their own air samples using inexpensive air monitors, and the publication of a new international study confirming the carcinogenicity of the popular pesticide glyphosate (“Round-Up”). Then author, climate scientist, biologist, and biosphere expert Dr. Tyler Volk talks about the tiny molecules that are actually causing all of our climate trouble.
