More on the
superweed story in today's
New York Times, including comments from Michael Pollan:
A few lessons may be drawn from this story:
1. A product like Roundup Ready soy is not, as Monsanto likes to claim, “sustainable.” Like any such industrial approach to an agronomic problem — like any pesticide or herbicide — this one is only temporary, and destroys the conditions on which it depends. Lucky for Monsanto, the effectiveness of Roundup lasted almost exactly as long as its patent protection.
2. Genetically modified crops are not, as Monsanto suggests, a shiny new paradigm. This is the same-old pesticide treadmill, in which the farmer gets hooked on a chemical fix that needs to be upgraded every few years as it loses its effectiveness.
3. Monocultures are inherently precarious. The very success of Roundup Ready crops have been their undoing, since so many acres were planted with the same seed, and doused with the same chemical, resistance came quickly. Resilience, and long-term sustainability, comes from diversifying fields, not planting them all to the same kind of seed.
