Dow Chemical wants to put out a new herbicide called Enlist Duo to combat so-called "superweeds" that have grown resistant to Roundup and are now spreading like... weeds. It's an absurd arms race (farms race?) against nature, which the Union of Concerned Scientists, among others, has been warning about for years.
Meanwhile, an enormous pro-industry propaganda arm muddies the debate with pseudo-scientific websites like the "Genetic Literacy Project" (part of the right-wing STATS organization) to fool clueless journalists. It's 1984-level disinformation trying to ensure that chemical companies can do whatever they want.
Farm workers are already exposed to ridiculous levels of toxic stuff, with predictable results, which rarely gets discussed in these debates. Hence panel three.
