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”).

If you aren’t familiar with the Global BioGeoChemical Cycle, tune in!
