Long-Term Risks of GE Trees Remain Unanswered

The following is a joint statement from Global Justice Ecology Project, Indigenous Environmental Network, Rural Coalition, Biofuelwatch and Canadian Biotechnology Action Network.

In an apparent effort to allay serious public and scientific concerns about contamination threats from genetically engineered (GE) trees, on Aug. 3 researchers at Oregon State University claimed they had genetically engineered sterility into poplar trees. The real story of the study, however, is that the risks of genetically engineering trees are too great and can never fully be known.


During the seven year field trial of GE poplars described in the study, small environmental variations resulted in significant differences between trees that had the same GE constructs and also found differences between GE trees over time. This all points to how trees cannot be reliably engineered to prevent contamination.

"This study confirms what we've known all along," said Anne Petermann, executive director of Global Justice Ecology Project and coordinator of the international Campaign to STOP GE Trees. "Trees are extremely complex, and fertility, which is one of the most important functions of any living organism, has been evolving in trees for millions of years. It is incredibly arrogant and dangerous to think that through genetic engineering we can override such a fundamental function as reproduction. Far from allaying fears, this research opens up serious new concerns."

The genus populus includes 25-35 different species of trees, many of which can breed with each other, and are found across North America and Europe. Poplars can also reproduce asexually and live for hundreds and sometimes thousands of years. Therefore this seven year study on GE poplar trees is seriously inadequate.

"We still have no information about the potential long-term impacts of sterile or attempted sterile GE poplars on pollinators, birds and other wildlife that depend on fertile flowers and pollen to survive," added Lucy Sharratt of the Canadian Biotechnology Action Network. "We know GE sterility traits are never going to be 100 percent reliable. What happens when sterility fails and allows GE trees to escape? Unreliable sterility technologies would enhance rather than remove the dangers of GE tree contamination."

BJ McManama of the Indigenous Environmental Network explained the implications of GE poplars for Indigenous Peoples:

"Aspen, cottonwood, and other poplar varieties are an integral part of our individual and collective history, physical well-being and spiritual ceremonies. For Native tribes in the U.S. Southwest, for example, the cottonwood is sacred and every part harvested is done so without killing or harming the tree. Freshly fallen branches provide bark used in teas, poultices, tinctures and salves and the leaf buds and flowers provide food in the early spring. Fundamentally changing these trees' genetic makeup violates Natural Law, our cultural traditions and subsistence rights."

Developing plantations of fast-growing trees like GE poplars for biofuel, biomass or other raw materials could lead to the accelerated destruction of forests for the development of these plantations, a trend identified in a study by the UN Food and Agriculture Organization. Target areas for this expansion in the U.S. are the Pacific Northwest and Midwest, where many GE poplar test plots already exist.

Fireworks have taken a lot of heat recently. In South Dakota, fire experts have said President Trump's plan to hold a fireworks show is dangerous and public health experts have criticized the lack of plans to enforce mask wearing or social distancing. Now, a new study shows that shooting off fireworks at home may expose you and your family to dangerous levels of lead, copper and other toxins.

Did you know that some snakes can fly?

The south Asian paradise tree snake (Chrysopelea paradisi) can launch itself into the air and glide from one tree branch to another. And when it does, it moves its body in waves in something known as aerial undulation. Scientists have long known how the snakes moved. But they didn't know why. Until now.

The oceans could look much emptier by 2100, according to a new study that found that most fish species would not be able to survive in their current habitat if average global temperatures rise 4.5 degrees Celsius by the end of the century, as The Guardian reported.

Independence Day weekend is a busy time for coastal communities as people flock to the beaches to soak up the sun during the summer holiday. This year is different. Some of the country's most popular beach destinations in Florida and California have decided to close their beaches to stop the surge in coronavirus cases.

For some combat veterans, the Fourth of July is not a time to celebrate the independence of the country they love. Instead, the holiday is a terrifying ordeal. That's because the noise of fireworks – loud, sudden, and reminiscent of war – rocks their nervous system. Daily fireworks in many U.S. cities in recent weeks have no doubt been interfering with the sleep and peace of mind of thousands of veterans.
