The USDA Just Cleared a Defective GMO Tree for Release into the Wild with Anne Petermann
Send us Fan Mail A genetically engineered (GE) chestnut modified with a wheat gene is being framed as a conservation breakthrough, but the reality is far messier and far more permanent. After the USDA deregulated the GE American chestnut for release, we asked the question regulators keep sidestepping: what does “safety” even mean when a tree can live for centuries, spread pollen for miles, and reproduce in ecosystems we cannot control? We speak with Anne Petermann of Global Justice Ecology Project and the Campaign to Stop GE Trees about the Darling 54 GE chestnut and its defects documented along the way, including loss of blight resistance, high mortality rates and other serious problems tied to the genetic engineering process. We also unpack the next regulatory hurdle at the Environmental Protection Agency, where the fungus-resistance trait could be treated as a plant-incorporated protectant, raising thorny issues around tracking, accountability, and the basic impossibility of recalling a self-spreading organism once it is loose in the wild. Then we step back and look at what’s already happening without genetic engineering: wild American chestnuts persisting and returning across the range, breeding work to strengthen natural blight resistance in wild American chestnuts, and a vivid on-the-ground example captured in our short film featuring naturalist Bernd Heinrich, where multiple generations of chestnuts are thriving and reproducing. We also dig into the controversy around GE chestnuts planted o the White House lawn, and why cross-border pollen drift puts Canada’s endangered chestnut population in the blast zone.
