Genetically Engineered Trees -
Genetic engineering of food crops has been a stealth technology; it went from 0 to 60 before we knew it - zero to 60 million acres - and with worldwide outcry is now holding steady at around 100 million acres. Meanwhile, the equally stealthy cousin of genetically engineered (GE) agriculture is poised for a similar explosive start: the genetic engineering of trees is proceeding in hundreds of test locations, and the possibility that the new genes spliced into GE trees will interfere with natural forests isn't a hypothetical risk but a certainty. During our lives, genetic engineering may do as much damage to forests and wildlife habitat as chain saws and sprawl.
This is not to say that every application of GE will necessarily be bad. There may be good uses for this technology; it may be possible to use it responsibly. But common sense should warn us that its commercial development in the absence of environmental safeguards is a prescription for disaster. Sierra Club opposes the out-of-doors deployment of genetic technologies because the genes are free -- as free as pollen on the wind -- to invade nature, and because once this has happened they can't be recalled. The arguments below are not intended to be inclusive but only to illustrate the nature of the problem.
Corporations, as Milton Friedman pointed out, exist not to be ethical but to make money. And from the standpoint of a forestry company, wildlife habitat has very little value. "Growing the bottom line" is what such companies try to do, and among their strategies are clear cutting and replanting with uniform and fast growing trees (tree plantations). An optimal match between the manufacturing process (cutting lumber and making paper goods) and the inputs can add to profits. These companies now see an opportunity to engineer trees which grow faster, contain less lignin, are more uniform in their characteristics, are more resistant to disease, and so forth. And unfortunately, if this is the way to make money, this is likely to be the future. Sierra Club believes that pressure from society in the form of legal prohibitions and restraints, stringent regulations and liability laws, and consumer activism must be brought to bear in order to hold the industry in check.
We are often told that commercialization of genetically engineered (GE'd) trees is at least several years away. This is also part of the "stealth" referred to above. GE'd stands of papaya trees are yielding commercial crops in Hawaii. The tip of the iceberg is already under our prow, not on the distant horizon. But it is for the traditional forestry industries of paper and lumber making that most research is presently being done. This is also an area which poses the greatest risk to nature.
The threat of GE'd trees interbreeding with wild trees is extreme. While many agricultural varieties are already quite different from their ancestors of thousands of years ago, this is not the case with trees. And genetically engineered trees could easily become invasive. Faster growing, limp, low-lignin trees resistant to common pests could easily become a kudzu-like threat, moving into our national parks and forests and changing their character forever.
Should we object if forestry companies do genetic engineering on their own land? Sierra Club opposes GE'd tree plantations on private land for all the same reasons we oppose other tree plantations. To put it briefly, tree plantations are not forests. This will be even more so of GE'd tree plantations. For instance, GE'd pines might be grown without all those "useless" pine cones. They may be herbicide resistant so that competing undergrowth can be eliminated. They may be pesticide resistant so that many of the insects which live in association with trees are poisoned. The result, then, may be a silent forest, one which doesn't support chipmunks or snakes at ground level, holding no birdsong in its branches, and with no raptors soaring above. Clearly, such a stand of trees is not really a forest. And worse, the damage can't be confined to private property as trees live for many years and can't be closely observed; "birth control" among trees is less reliable than among people and even genetic engineering can't guarantee that a branch won't decide to manufacture pollen. Pine pollen can blow hundreds of miles on the wind.
Should we oppose genetic "improvements" to trees on public lands? Sierra Club believes that we can't allow the industry to be judged by its hype and that patented genes are not an improvement over nature. We also must avoid only judging what one gene may do, because once hundreds of different genes -- most of them patented by industry and enjoying protection as "private property" -- are allowed access to public lands, the consequences of unintended combinations will be unpredictable.
GE trees will also be a danger in other nations, particularly in the underdeveloped world where conditions for effective regulation often don't exist.
For all of the above reasons, action is needed both at home and internationally to create a worldwide moratorium on the further development and planting of GE trees at least until an effective framework for public debate, unbiased scientific evaluation, and regulation in the public interest -- with the goal of preserving biodiversity -- can be brought into being.
If you agree with the above, does this make you a Luddite? This is an unfair characterization by our opponents. Sierra Club does not oppose the use of genetic science in indoor research or medical applications. Our policy about genetic research is that there should 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 by industrial secrecy provisions. We believe genetic technology belongs indoors, with containment, not out in the fields.
We would also point out that the United States is using twice as much paper per capita as other highly civilized nations (Europe, Japan). Let us not ask genetic engineering to do what could be accomplished by lower-tech means like putting a surcharge on junk mail.
Just as there are powerful economic incentives behind logging on public lands, sprawl, and other activities which Sierra Club opposes, there are similar incentives behind genetically engineered sylviculture. Not only are landed property rights and business rights involved, but also the patent rights to genetic code which are now privatizing the genetic heritage of our planet. It is Sierra Club's task, as always, to oppose such interests and to fight for the right of nature to exist for itself, and of future generations to enjoy and be inspired by it.
