Tyrone Hayes has been coming to Minnesota a lot over the last couple of years to discuss his research connecting Atrazine, a herbicide used widely in corn fields in the U.S., to deformities in frogs. He’s testified at the legislature, been at the heart of controversy with the MPCA, and basically made it his job to educate all he can about why we shouldn’t be using Atrazine. He’s a good presenter to boot. He spoke last March at the Humphrey Institute at a program sponsored by MEP member group Friends of the Mississippi River. FMR now has the video online.
