Today, nearly 100 years since these memorable words were penned, the genetic sanctity and survival of our planet’s trees are at risk. Several countries around the world, including our own Canada, have embarked upon a biotechnological journey that may be leading us down the path of genetic devastation for our natural forests and trees.
Concerns about genetically engineered foods and industrial crops continue. At the same time we must face the reality of another, potentially greater, threat to planetary biodiversity – genetically engineered (GE) trees.
Rooted in Money
Surfing the Canadian Forest Service (CFS) website (www.nrcan.gc.ca/cfs), it is disconcerting to find evidence that the federal agency entrusted with the safe keeping of our nation’s forests has become an enthusiastic supporter and promoter of genetically engineered trees.
The FAQ pages (Frequently Asked Questions) of the CFS site ask and answer the question: “Why are genetically engineered trees being produced? The objective is to produce more healthy trees on a smaller land base. Present levels in the demand for wood will double by the year 2020. Genetically engineered trees can be used in intensively managed plantations to decrease the effect of human pressure on our ecosystems while increasing the competitiveness of Canada’s forestry industry.”
The forest industry’s keen interest in and promotion of genetically altered trees hinges upon the quest for significant monetary benefits. For instance, by controlling certain economically relevant traits, such as decreasing lignins – lignins are the naturally occurring chemical compound in wood that strengthens cell walls – and increasing growth rates, profits to the pulp and paper industries could improve significantly.
The subtext of government and industry’s combined GE tree message is: “Trust us, we know best. Monocultural plantations of genetically engineered trees will save our native forests. First we will cut down that messy, unpredictable hodgepodge of all kinds and shapes and sizes of trees that’s growing out there now. Then we will plant our new, improved trees! Rows upon rows upon rows, perfectly spaced for easy cutting; all genetically programmed to survive the pesticides, herbicides and fungicides we will need to douse them with. They will all grow to the same height and width, in the same time, and will all have the same ‘novel traits’ we have engineered into them in order to maximize our profits.”
This cheerleader mentality of rooting for a very new and untested biotechnology is deeply disturbing for a variety of reasons. One obvious reason is the assumption and promotion of the unproven premise that the benefits of growing and harvesting genetically engineered trees outweighs the risks and hazards. This is yet another example of governments, corporations and possibly academics disregarding the universal precepts of the precautionary principle. The precautionary principle is included in the Canadian Environmental Protection Act and in the environmental charters of many other nations for good cause: to protect the environment and future generations against threats of serious or irreversible damage.
The forest industry seems to have adopted a hybrid language that obscures their intentions to make GE tree plantations a part of the Canadian landscape. Less than 10 years ago, a newsletter published by the Poplar Council of Canada (PCC) dated July 1998 and still displayed on their website (www.poplar.ca) proudly told its trade members to prepare for the next big thing in forest management: genetic engineering. Blatantly touted as the answer to bigger profits and more industry-friendly timber, GE trees were openly endorsed and raised as the sceptre of the future of forest management. Newsletter excerpts from PCC reveal a condescendingly patriarchal undertone to the effect that the only thing standing in the way of this pre-arranged marriage between biotechnology and the forest industry were the ignorant, fearful public. The code text might indeed read: ‘Those damned consumers and pesky conservationists… why don’t they get out of our way and let us run the forests.’
The ensuing public rejection of GE crops undoubtedly led PCC to adopt a more subdued but nonetheless enduring strategy for introducing GE trees to Canadians.
But with the recent flush of international recognition (Science, September 15, 2006), tree genome researchers are systematically targeting the forestry industry as a funding resource. A June 2006 paper prepared for Genome Canada and presented to PCC by Barb Thomas and Jim Richardson, titled “Poplar Genomics to Poplar Production: Bridging the gap for best use of our resources and knowledge” highlights many potential benefits to this academic-corporate union. A cozy triad of government, forestry industry stakeholders and academic biotechnology researchers is developing, poised to promote the public acceptance of GE trees.
GE Trees in Canada
Thus far, there has been no recorded release of GE trees in Canada. But there is definitely research being conducted. According to the David Suzuki Foundation (www. davidsuzuki.org), four “confined” GE tree research trials are underway. All located in Eastern Canada, these trials include two test plots of GE poplars, one plot of GE Black Spruce and a plot of White Spruce with an insecticidal gene from Bacillus thurningiensis (BT). Note that many scientists, including Dr. Suzuki, are concerned that pollen from outdoor GE trees can never be entirely safely confined. In Canada, GE plants and trees are regulated by the Canadian Food Inspection Agency (CFIA). The CFIA is currently updating the “Guidelines for Confined Field Trials of Forest Tree Plants with Novel Traits” and has invited consultation from tree improvement associations and academic, federal, provincial, territorial and private forest sectors. No mention of invited public input can be found on the CFIA site.
Global Resistance to GE trees
The worldwide outcry to ban the release of GE trees into the environment is getting stronger and louder. Angry public scorn has led to vandalism of laboratories and field sites containing genetically modified trees in several countries including the USA and Canada. Forest accreditation bodies, including the Forest Stewardship Council, have also expressed concern about the use of transgenic trees and will not certify plantations that contain research trials of transgenic trees.
Last April (2006) mounting international concerns led delegates to the United Nations Convention on Biological Diversity to pass a formal UN declaration urging caution on GE trees. Greenpeace International’s submission to the convention stated that the risk of harmful environmental effects from transgenic forest trees is considerably greater than from shorter-lived GE crops, particularly because trees can reproduce many times before they are harvested. The submission provided evidence on ecological risks associated with transgenic forest trees, calling them “significant and likely to prove unmanageable and irreversible.”
The submission further stated “Greenpeace is opposed to the release of genetically engineered organisms into the environment at the present state of knowledge and calls for a ban on the release of transgenic trees. As an interim measure a global moratorium on commercial releases and on larger scale experimental releases is recommended.”
The impact of “out-of-the-lab” GE trees is yet to be fully determined, but a determined consortium of environmental health organizations has called for a global moratorium on the commercial release of genetically modified trees until further research has been conducted.
Sierra Club’s website states the organization “does not oppose the use of genetic science in indoor research or medical applications. Our policy about genetic research is that there should be more of it, more of it aimed at answering questions about long term effects on health and the environment, and less of it shielded as ‘confidential business information’ as at present. We believe genetic technology belongs indoors, with containment, not outdoors in fields and forests.”
The Geography of GE Trees
The GE tree threat is worldwide. A preliminary list of GE trees in various stages of research and development was compiled by Dr. Neil Carman of the Sierra Club Genetic Engineering Committee in 2005. The list reveals that hundreds of field trials and genetic engineering laboratory efforts are under way around the world to commercially develop GE trees (www.mindfully. org).
Based on information from Global Justice Ecology (www. globaljusticeecology.org), the United States has 150 GE tree test plots and conducts over two thirds of the world’s GE tree research. China is believed to currently be the only country where commercial GE tree plantations exist. They are unregulated; GE trees can be bought at nurseries and planted anywhere. Chile may be next in the queue of countries wanting to commercialize GE trees.
Rooting for the Future of Trees
The poem “Trees” is probably the most quoted poem in American history. Its opening couplet has been deeply planted in the psyche of millions of people. And for good reason. Trees have held a revered place in all cultures as universal symbols of life, abundance and fertility. They play a critical role in sustaining the health of our planet’s ecosystem.
We must stand together, roll up our sleeves and continue to do whatever it takes to preserve the biodiversity of our planet’s trees.
7 Reasons GE Trees Are Dangerous to the Health and EcoCulture of Our Forests
1. Uncontrollable cross-pollination
The threat of GE trees interbreeding with wild trees is extreme. Tree pollen can be blown by the wind and drift on air currents for hundreds, possibly thousands, of kilometres from its source. This can lead to unintentional but irreversible cross-pollination and the spread of genes from transgenic trees to unmodified trees, native, wild and cultivated alike. Evidence of significant cross-pollination between genetically engineered crops and wild varieties has already been shown in corn, rice and canola. Although scientists hope to create sterile GE trees to prevent pollination of native trees, it is not 100% assured.
2. Ecosystem disruption
Trees which have been genetically modified for plantation planting to produce specific commercially advantageous traits could prove devastating to natural tree populations. Subsequent offspring from cross-breeding could alter the way trees cycle nutrients and water. Genetically modified plantation trees developed for high growth rates absorb more nutrients and moisture than traditional varieties. This depletion creates a threat to the productivity of the land. Low lignin GE trees (or their hybrid offspring) would also decompose far more quickly, which would alter soil structure, ecology and fertility.
3. Toxic properties
Novel traits such as insect and fungal resistance and low lignin content produced through genetic engineering could harm natural tree species. For example, beneficial insects could be poisoned by genetically produced biopesticides and the application of stronger pesticides designed specifically for application to GE trees. Other native forest species including fungi (mushrooms), insects and birds would be negatively impacted through toxicity and food supply reductions.
4. “Super pests”
Trees bred with biopesticide properties are of particular concern to the health of the many beneficial insects living in our forests. This genetically engineered trait allows for greater tolerance to toxic pesticide use and also has the potential to lead to the creation of pesticide-resistant “super pests” that would be especially harmful to unprotected, natural plants.
5. “Super weeds”
Another novel trait manipulated in the production of some GE trees is herbicide tolerance. There are concerns that this trait would allow for and actually encourage the greater use of toxic herbicides in the growing of plantation trees. Like rampant pesticide use, the excessive application of herbicides could reduce biodiversity by killing other plants, lead to an increase in the growth of resistant types of weeds, as well as polluting soil and water.
6. Patented monopolies
Smaller wood lot managers and timber producers will be faced with the same economic risks and outcomes as those associated with growing genetically engineered agricultural crops such as corn and soy. Transgenic trees, like their bioengineered food crop counterparts, will be patented, which could quickly lead to a monopoly of large timber corporations controlling the industry.
7. Silent forests, unlivable habitat
When trees are grown purely for the sake of commercial traits, natural reproduction through seed dispersal from pine cones and similar structures is potentially eliminated. Without seeds to eat, many forest creatures have no food source. Transgenic trees with herbicide resistant traits will promote the use of stronger herbicides to eliminate forest bed undergrowth which normally provides habitat and food for a wide range of forest dwelling creatures. While herbicides and pesticides are already being used with non-GE species, it is thought that GE tree plantations will exacerbate their use. Trees engineered to produce their own pesticides will create a poisonous environment for the myriad insects and other small creatures such as spiders, litter layer crustaceans, worms and mulluscs living in association with trees. The net result? Silent, toxic, uninhabitable forests.
