GMO Chestnuts in Chestnut Ridge Park?

This Op-Ed, written by GJEP Executive Director Anne Petermann was published in The Public, a local weekly paper in Buffalo, NY in response to articles in the Buffalo News extolling the virtues of using GE American chestnuts as part of a campaign to bring American chestnut trees back to a local park.

While the article is targeted to Western New York, the questions and concerns are applicable across the eastern US where researchers want to release GE chestnuts throughout the native forests of the region.

Self-replicating, unregulated GMOs in our forests, what could go wrong?

This spring Erie County Executive Mark Poloncarz took part in an Arbor Day activity that planted 50 American chestnut trees in the park as part of a reintroduction campaign to bring the park’s namesake trees back.

Unfortunately, a future phase of the plan involves introducing risky GMO American chestnut trees to the park in the misguided belief that this is the only way to restore the species and make it resistant to the blight that killed the trees in the early 1900s.

GMO Proponents ignore the potential dangers of planting these unnatural American chestnut trees in the forest. They also overlook the fact that, outside of labs and test plots, GMO trees are not legal.  In fact, the only countries in the world genetically engineered forest trees are legal for use are China and Brazil.

There has been widespread global public outcry against the social and ecological dangers posed by genetically engineered trees, and even the United Nations has warned against their use.  In the US last July, 284,000 people submitted comments to the USDA demanding they reject legalization of a genetically engineered eucalyptus tree.

If approved by the government, the GMO American chestnut tree would be the first ever self-replicating GMO to be released directly into the wild for the purpose of contaminating as many wild relatives as possible.  It would be one giant uncontrolled experiment and set a dangerous precedent for the future our forests and natural environment.

It is clear that some researchers are eager and confident in the outcome of their experiment, but the interests of science alone cannot be enough to take an irreversible action that involves the world’s first release of a self-replicating genetically modified organism, the long-term risks of which are completely unknown.  History has shown us that just because science can do something does not always mean it should.  Our scientific and technological choices must be informed by broader ethical, health and environmental considerations.

And while these researchers insist that their genetically engineered American chestnuts are the only way to go, there are numerous initiatives working to restore the American chestnut naturally through traditional breeding techniques.  But GMO chestnut proponents complain that this process is too slow, while downplaying the risks and unknowns of these trees.

We know from GMO crops that genetic engineering comes with unintended problems. Widespread use of herbicide resistant GMO corn and soy, for example, led to the evolution of herbicide-resistant super weeds—and hence to the use of even more toxic herbicides.

But in the case of the GMO American chestnut, we are not talking about an annual plant in a field, we are talking about a tree that can live 250 years and spread pollen and seeds for miles.

Forest ecologists will tell you how very little we know about forest ecosystems.  The complex interactions between trees, soil microorganisms, wildlife, songbirds, and insects are barely understood.  There is no way to know what the risks will be of planting GMO trees in forests. If something goes wrong in 20, 30 or 50 years, the impacts will be irreversible.

If we truly want to protect our forests, we should be combatting climate change and stopping the global trade in raw logs, woodchips, and live trees that is importing the diseases, insects and invasive species that are wreaking havoc. Adding unnatural and risky genetically engineered trees and their unpredictable impacts will only worsen the problem.

Tell County Executive Mark Poloncarz to reject dangerous genetically engineered American chestnut trees and to support only the efforts to restore them naturally.
