Forests Are About to Become Genetically Modified


  • Scientists have been working since the early 1990s to develop a genetically altered American chestnut tree resistant to a fungus that all but wiped out the species
  • The forests along the U.S. east coast were once home to billions of American chestnut trees that provided sustenance for animals and humans
  • Farmers used to fatten their hogs and cows by allowing them to forage for chestnuts in the fall; people in the Appalachian Mountains would harvest and sell the chestnuts
  • A release of GE trees would open the door to release other genetically engineered plants in the forest. It is impossible to monitor the GE trees or predict how they will impact the environment

Since long before the first settlers arrived in North America until the mid-1950s, there were billions of American chestnut trees (Castanea dentata) blanketing the forests from Maine to Florida.1 The deciduous trees could grow more than 100 feet tall and span 9 feet around. In fact, a lone chestnut estimated at 100 years old, was discovered in Maine in 2015, measuring out to a towering 115 feet tall.2

Although majestic to see, the trees also produced edible nuts that could be ground into flour, stewed into puddings or roasted and eaten out of the shell. Early Native Americans used the leaves for medicinal treatments and the wood was the first choice for pioneer log cabins.

Many times, the first 50 feet of the trunk was clean, without branches or knots, making it a builder’s dream.3 The trees grow fast and did not rot, so were a good choice for telephone poles and railroad ties.

The New York Times reports that in 1915, one author estimated it was the “single-most-cut tree” in America. As North America was settled, the American chestnut trees were the basis of Appalachian subsistence farming. New York Times reports that in 2005, historian Donald Davis wrote:4

“With the death of the chestnut, an entire world did die, eliminating subsistence practices that had been viable in the Appalachian Mountains for more than four centuries.”

The American chestnut tree also provided food for animals in the forest, including deer, squirrels and bears.5 Unlike oak trees with irregular acorn cycles,6 chestnut trees produce every year. Local farmers would send their hogs and cattle to forage on the chestnuts that had ripened and fallen to the ground in the late fall.7

Chestnut Blight Reduced Majestic Trees to Shrubs

Near the turn of the 20th century, a fungus that has all but eradicated the mature American chestnut trees was introduced into the U.S. through infected, imported nursery stock from China.8,9 The U.S. Department of Agriculture National Invasive Species Information Center reports the blight was identified for the first time on dying chestnut trees in the Bronx Zoo.

The fungus was named Cryphonectria parasitica and may have arrived as early as 1893.10 It wasn’t long afterward that states began reporting dying American chestnut trees.11 Currently, the trees are so rare that discovery of an American chestnut tree in the wild rates a report in the national press.

However, as The American Chestnut Foundation reports, the tree has not gone completely extinct but, rather, is considered “functionally extinct” since the fungus does not affect the root system.12 The American chestnut is highly susceptible to the fungus as is the European chestnut. But the Chinese chestnut tree has some resistance to the infection as it causes only a small canker in the bark.13

The fungus is an ascomycete,14 also known as sac fungi since it has a sac-like structure with four to eight ascospores in the sexual stage. Some of the largest and more commonly known ascomycetes are morel mushrooms and truffles. Other pathogens in the same group include those that cause Dutch elm disease and apple scab.15

The fungus can infect a tree through small injuries to the bark, some as small as those created by insects.16 The fungus then grows under the bark and produces yellow-brown blisters. The infection eventually makes its way around the trunk, cutting off nutrients and water.17

The infection is called a blight, potentially because the branches die quickly. However, the fungus can infect branches, stems and a trunk of any size. It grows rapidly and continues to grow after the tree has died.18

Since the disease does not affect the roots of the tree, the species continues to survive by sending up sprouts through the stump. Inevitably, however, they succumb to the disease. Yet, a USDA Forest Service survey found there may be 60 million of these sprouts growing in the forests of New York state.19

How Genetically Engineered Chestnut Trees Were Birthed

Although the U.S. has lost other plants and animals to extinction, the American chestnut tree appears to have an emotional hook that has driven some to produce a genetic modification in the hope of bringing back large stands of the trees. The New York Times reports this may have started in 1989 when Herb Darling received a call telling him of an American chestnut tree on his property.20

The tree was five stories high and about two feet wide, but also was dying from the fungal disease. Unable to save the tree, he decided to save the seeds. But since the tree wasn’t making any, he went about finding a male tree to fertilize the flowers in the spring.

After one failed attempt to fertilize the flowers, the tree produced about 100 nuts. He planted some and sent the others to Charles Maynard and William Powell, tree geneticists from State University of New York College of Environmental Science and Forestry. Thus began the movement to engineer a new American chestnut tree that might be resistant to the blight.

Although the intent may be rooted in the desire to see these trees begin to repopulate the forests, ultimately the results may be disastrous. Initially, Darling looked for support from The American Chestnut Foundation, but the group was wary of genetic engineering.

The first attempt at inserting an antimicrobial compound into the tree genes originated from frogs. After several years, this was abandoned when the team feared the public would have problems with a tree containing amphibian genetics. The next step was to look for a single resistance gene in the Chinese chestnut tree that didn’t have trouble with the fungus.

However, as the scientists discovered, the Chinese chestnut tree is a complex organism that uses multiple genes to protect against the blight.21 In 1997, Powell found a scientific paper describing how the insertion of one gene from wheat expressed oxalate oxidase that protected a plant against oxalate-producing fungus, which the chestnut fungus produced.

Scientists Frustrated by Regulations to Protect the Forest

In 2013, the team announced their success in creating a version of the American chestnut tree that could defend against Cryphonectria parasitica.22 Each successive iteration of the tree has been named after Darling. This one is the Darling 58.

In 2018, Powell spoke at a chapter meeting of The American Chestnut Foundation to talk about his three-decadeslong research project. He warned the attendees that as many of the technical obstacles of producing a transgenic tree resistant to Chestnut blight had been overcome, they now face their biggest challenge: approval to plant a transgenic tree in the wild.

The approval process began with a 3,000-page report to the branch at the USDA responsible for regulating genetically engineered plants. The team also plans to file petitions so the FDA can examine the food safety of the nuts and with the EPA to review the impact the tree may have under Federal pesticide law. The New York Times reported a conversation during the meeting:23

“‘This is more complicated than science!’ someone in the audience said. ‘It is,’ Powell agreed. ‘Science is fun. This is frustrating.’ (‘Being regulated by three different agencies is kind of overkill,’ he told me later. ‘That really stifles innovation in environmental conservation.’)”

It is crucial to remember that releasing genetically engineered organisms into the wild comes with a risk. While researchers may be frustrated by the regulations, without at least the minimal oversight now in effect, the food supply could be sorely impacted.

As it is, there is a significant percentage of the foods you purchase at the grocery store that contain some form of genetically engineered ingredients. The Center for Food Safety lists potential unexpected health risks that may be posed by genetically altering human and animal food. These include:24

  • Toxicity
  • Allergic reactions
  • Antibiotic resistance
  • Immunosuppression and cancer
  • Lack of nutrition

Scientists Have Not Identified the Impact of GE Trees

However, while the scientists told The New York Times they plan to submit a report to the FDA for judgment about food safety of the chestnuts, Gary Ruskin, co-director of US Right to Know, writes that the FDA has repeatedly made it clear that they do not test whether genetically engineered foods are safe.25

“As Jason Dietz, a policy analyst at FDA explains about genetically engineered food: ‘It’s the manufacturer’s responsibility to insure that the product is safe.’ Or, as FDA spokesperson Theresa Eisenman said, ‘it is the manufacturer’s responsibility to ensure that the [GMO] food products it offers for sale are safe …’”

In a white paper produced by The Campaign to STOP GE Trees, Biofuelwatch and Global Justice Ecology Project, they propose the GE American chestnut tree is a test case to determine if the public will “support biotechnology for forest conservation,” paving the way for more GE trees. They quote geneticist David Suzuki, who says:26

“We’re still at the very beginning of understanding what we’re doing. The rush to apply these [genetic engineering] ideas is absolutely dangerous, because we don’t have a clue what the long-term impacts of our manipulations are going to be.”

As Powell and Maynard push forward with the current support of The American Chestnut Foundation and others interested in populating the forest with genetically engineered trees, The Campaign to STOP GE Trees brings to light many of the questions regarding safety and the future of the environment that have not been addressed.27

“Locating and monitoring the progress of all the GE AC trees and their progeny will be near impossible, especially over a long period of time. There has been some discussion of planting the GE trees slowly, in stages, to improve the potential for monitoring. However, common sense and past experience with genetically engineered crops suggests that monitoring is not feasible.

A release of GE AC trees into natural forests raises some important questions and concerns about potential risks. For example: Will the nuts from GE AC be safe to eat? Will GE AC be safe for soils, waterways, fungi, pollinators, and other animal and plant species in the forest ecosystems where they grow?

Will inhaling pollen from GE chestnut be harmful? Will introducing GE AC present risks to the few remaining native AC trees, or those in hybrid backcross breeding program orchards?

Bees, butterflies, squirrels, birds and humans can carry away tree nuts and pollen, and pollen can also be blown on the wind. Once the engineered trees are released into forests, the GE AC ‘experiment’ will be irreversible. There is no way to prevent the trees from spreading, including across cultural or jurisdictional boundaries.

Before we can evaluate the risks, we must first ask: do we have the tools, information, time and wisdom to conduct adequate risk assessments? Only then can we determine whether the risks are worth taking.”

Biotechnology May Derail Natural Initiatives

Anne Petermann wrote in the Scranton Times-Tribune that planting these genetically altered trees opens the door for other risky genetically engineered plants. The fact is a wild tree cannot be replaced by a genetically altered facsimile. Peterman says this is “not restoration, but an uncontrolled experiment with our forests.”28

It is impossible to have the American chestnut trees in numbers that were living in the early 1900s. However, there are other areas of research currently underway to help the species recover. The first is breeding for resistance. Researchers have experimented with crossbreeding Chinese chestnut trees with the American chestnut.29

However, the Chinese chestnut is much shorter and spreads wide instead of going tall and straight. While the process has been slow, The American Chestnut Foundation has had some success in developing a hybrid that is 15/16 American chestnut with selection for resistance and form. They are boosting seed production of a line of trees that appear to be blight-resistant to plant at test sites.

Another line of research has been aimed at lowering the virulence of the fungi. Experiments with infected European chestnut trees show the fungi had developed hypovirulence or had become less toxic to the trees. Researchers found double-stranded RNA within the fungi they later discovered was a virus. The virus caused the fungus to become less virulent.

This treatment has shown some promise in Europe and Michigan. Unfortunately, it has not had the same success along the eastern shores of North America. Researchers have been able to therapeutically treat individual infections, but using this strategy at a population level depends on nature. Petermann believes the genetically altered trees threaten to derail the reintroduction of natural trees.30

“Because the GE chestnuts were developed in a lab in a way that could never occur in nature (forcing genes from unrelated wheat plants into the DNA of trees), there is no way to know how they will respond in nature.

In fact, the researchers who promote these trees have done no long-term risk assessments to determine how these trees will interact in a natural forest over time, or how they will impact human health.”

The petition to deregulate the Darling 58 American Chestnut tree was submitted to the USDA January 17, 2020.31 The Campaign to STOP GE Trees developed several talking point samples to be used when the Animal and Plant Health Inspection Service was accepting comments.32 The deadline for public comments was October 19, 2020. At this time the USDA is reviewing the comments before making their ruling.

Biotech Companies Gain Power by Taking Over the Government

There is no doubt in my mind that GMOs and the toxic chemicals used along with them pose a serious threat to the environment and our health, yet government agencies turn a blind eye and refuse to act — and the reason is very clear: They are furthering the interests of the biotech giants.

It is well known that there is a revolving door between government agencies and biotech companies like Monsanto-now-Bayer. Consider the hypocrisy of the FDA. On paper, the U.S. may have the strictest food safety laws in the world governing new food additives, but this agency has repeatedly allowed GMOs and their accompanying pesticides and herbicides like Roundup to evade these laws.

In fact, the only legal basis for allowing GE foods to be marketed in the U.S. is the FDA’s claim that these foods are inherently safe, a claim which is patently ridiculous. Documents released as a result of a lawsuit against the FDA reveal that the agency’s own scientists warned their superiors about the detrimental risks of GE foods. But their warnings fell on deaf ears.

The influence of the biotech giants is not limited to the U.S. In a June 2017 article, GMWatch revealed that 26 of the 34 members of the National Advisory Committee on Agricultural Biotechnology of Argentina (CONABIA) are either employed by chemical technology companies or have major conflicts of interest.

You may be aware that Argentina is one of the countries where single-crop fields of GE cotton, corn and soy dominate the countryside. Argentina is also a country facing severe environmental destruction. Argentines are plagued with health issues, including degenerative diseases and physical deformities. It would appear that the rapid expansion of GE crops and the subsequent decline in national health indicators are intrinsically linked.

Don’t Be Duped by Industry Shills!

Biotech companies’ outrageous attempts to push for their corporate interests extend far beyond the halls of government. In a further effort to hoodwink the public, Monsanto/Bayer and their cohorts have been caught zealously spoon-feeding scientists, academics and journalists with questionable studies that depict them in a positive light.

By hiring “third-party experts,” biotech companies are able to take information of dubious validity and present it as independent and authoritative. It’s a shameful practice that is far more common than anyone would like to think. One notorious example of this is Henry Miller, who was thoroughly outed as a Monsanto shill during the 2012 Proposition 37 GMO labeling campaign in California.

Miller, falsely posing as a Stanford professor, promoted GE foods during this campaign. In 2015, he published a paper in Forbes Magazine attacking the findings of the International Agency for Research on Cancer, a branch of the World Health Organization, after it classified glyphosate as a probable human carcinogen. After it was revealed that Miller’s work was in fact ghostwritten by Monsanto, Forbes not only fired him, but also removed all of his work from its site.

Industry front groups also abound. The Genetic Literacy Project and the American Council on Science and Health were both Monsanto-funded before Bayer bought Monsanto. Whether that funding continues under Bayer is left to be seen, but other “trusted” sources were also caught taking Monsanto money.

For example, WebMD, a website that is often presented as a trustworthy source of “independent and objective” health information, was exposed acting as a lackey for Monsanto by using its influence to promote corporate-backed health strategies and products, displaying advertisements and advertorials on Big Biotechs’ behalf, furthering the biotech industry’s agenda — all for the sake of profit.

But even with underhanded tactics to peddle their toxic products, biotechs are now unable to hide the truth: Genetic engineering will in no way, shape or form make the world a better place. It will not solve world hunger. It will not increase farmers’ livelihoods. And it most certainly will not do any good for your health — and may in fact prove to be detrimental.

There’s No Better Time to Act Than NOW — Here’s What to Do

So now the question is: Will you continue supporting the corrupt, toxic and unsustainable food system that Big Biotech, Monsanto/Bayer and their industry shills and profit-hungry lackeys have painstakingly crafted? It is largely up to all of us, as consumers, to loosen and break their tight hold on our food supply. The good news is that the tide has turned.

As consumers worldwide become increasingly aware of the problems linked to GE crops and the toxic chemicals, herbicides and pesticides used on them, more and more people are proactively refusing to eat these foods. There’s also strong growth in the global organic and grass fed sectors. This just proves one thing: We can make a difference if we steadily work toward the same goal.

One of the best things you can do is to buy your foods from a local farmer who runs a small business and uses diverse methods that promote regenerative agriculture.

You can also join a community supported agriculture (CSA) program, where you can buy a “share” of the vegetables produced by the farm, so you get a regular supply of fresh food. I believe that joining a CSA is a powerful investment not only in your own health, but in that of your local community and economy as well.

In addition, you should also adopt preventive strategies that can help reduce the toxic chemical pollution that assaults your body. I recommend visiting these trustworthy sites for non-GMO food resources in your country:

Organic Food Directory (Australia) Eat Wild (Canada)
Organic Explorer (New Zealand) Eat Well Guide (United States and Canada)
Farm Match (United States) Local Harvest (United States)
Weston A. Price Foundation (United States) The Cornucopia Institute
Demeter USA American Grassfed Association

Monsanto, Bayer and their allies want you to think that they control everything, but they do not. It’s you, the masses, who hold the power in your hands. Let’s all work together to topple the biotech industry’s house of cards. Remember — it all starts with shopping smart and making the best food purchases for you and your family.
