Open Letter from World Scientists to All Govts
Open Letter from World Scientists to All Governments
Summary
We, the undersigned scientists call for the immediate suspension of all environmental releases of GM crops, both commercially and in open field trials, for at least five years; and for patents on organisms, seeds, cell lines and genes to be revoked and banned.
Patents on life-forms are allowing corporations to pirate intellectual and genetic resources from Third World nations and increasing corporate monopoly on food production and distribution. GM crops are not necessary to feed the world. There is already more than enough food for everyone. What we need is an end to food monopoly and a more equitable distribution.
The public have been promised miracle GM crops that will fix nitrogen, resist drought and improve yield. Instead, the only crops on offer are engineered to be tolerant to wide-spectrum herbicides manufactured by the same corporations, or are engineered with bt-toxins to kill insect pests. The latest largescale survey of GM crops showed they offered no benefits. On the contrary, they yield significantly less and require the use of more herbicides.
The hazards of GM crops are now becoming apparent, and some of them are acknowledged by sources with the UK and US Governments. The herbicides used with herbicide-tolerant crops destroy biodiversity and are toxic to many
animals including human beings. Herbicide-tolerant GM crops have become
weeds and created further weeds by cross-pollination. The bt-toxins harm beneficial insect-pollinators, and have also led to widespread evolution of resistance among insect pests.
The horizontal spread of antibiotic resistance marker genes from GM crops has already been recognised as a serious hazard that will compromise the
treatment of life-threatening infectious diseases which have come back worldwide. New findings show that the horizontal spread of marker genes and other transgenic DNA can occur, not only by ingestion but via breathing in pollen and dust. The cauliflower mosaic viral promoter, widely used in GM crops, may enhance horizontal gene transfer and has the potential to generate new viruses that cause diseases.
All commercial plantings and open field trials should be halted. They are hazardous as the spread of transgenic pollen cannot be controlled. At the same time, the field-trials will produce no useful results because the protocols are inadequate. No attempts are being made to monitor for horizontal gene transfer or for impacts on public health.
There is an urgent need for research into sustainable agricultural methods that do not require GM crops. Many of these systems have already resulted in increased yields and diminished environmental impacts around the world. * * *
We, the undersigned scientists, call for the immediate suspension of all
environmental releases of GM crops, both commercially and in open field trials, for at least 5 years; and for patents on organisms, seeds, cell lines and genes to be revoked and banned [1].
1. Patents on life-forms are allowing corporations to plagiarise indigenous knowledge and plunder genetic resources from Third World communities, and at the same time, increasing corporate monopoly on food which is destroying livelihoods of family farmers all over the world.
2. It is becoming increasingly clear that the current GM crops are neither needed nor beneficial. They are a dangerous diversion from the real task of providing food and health around the world.
3. The promises to genetic engineer crops to fix nitrogen, resist drought, improve yield and to 'feed the world' have been around for at least 30 years. Such promises have built up a multibillion-dollar industry now controlled by a mere handful of corporate giants.
4. The miracle crops have not materialised. Instead, two simple characteristics account for all the GM crops in the world [2]. More than
70% are tolerant to broad-spectrum herbicides, with companies engineering plants to be tolerant to their own brand of herbicide, while the rest are engineered with bt-toxins to kill insect pests. A total of 65 million acres were planted in 1998 within the US, Argentina and Canada. The latest surveys on GM crops in the US, the largest grower by far, showed no significant benefit. On the contrary, the most widely grown GM crops -herbicide-tolerant soya beans - yielded on average 6.7% less and required two to five times more herbicides than non-GM varieties [3].
5. According to the UN food programme, there is enough food to feed the world one and a half times over. World cereal yields have consistently outstripped population growth since 1980, but one billion are hungry [4]. It is on account of corporate monopoly operating under the globalised economy that the poor are getting poorer and hungrier. Family farmers all over the world have been driven to destitution and suicide, and for the same reasons. Between 1993 and 1997 the number of mid-sized farms in the US dropped by 74,440 [5], and farmers are now receiving below the average cost of production for their produce [6]. Four corporations currently control 85% of the world trade in cereals [7].
6. The new patents on seeds will intensify corporate monopoly by preventing farmers from saving and replanting seeds, which is what most farmers still do in the Third World. Christian Aid, a major charity working with the Third World, concludes that GM crops will cause unemployment, exacerbate Third World debt, threaten sustainable farming systems and damage the environment. It predicts famine for the poorest countries [8]. The picture is just as grim for the developed world. A coalition of family farming groups in the US have declared their opposition to GM crops and corporate ownership of life-forms through patenting. They are demanding a moratorium on all corporate mergers and acquisitions, a moratorium on farm closures, and an end to policies that serve big agribusiness interests at the expense of family farmers, taxpayers and the environment [9].
7. The hazards of GM crops are now becoming apparent, and some of them are acknowledged by sources within the UK and US Governments. For example, the UK Ministry of Agriculture, Fisheries and Food (MAFF) has admitted that the transfer of GM crops and pollen beyond the planted fields is unavoidable
[10], and this has already resulted in herbicide-tolerant weeds [11]. Bt-resistant insect pests have evolved in response to the continuous presence of the toxins in transgenic plants throughout the growing season, and the US Environment Protection Agency is recommending farmers to plant up to 40% non-GM crops in order to create refugia for non-resistant insect pests [12]. The broad-spectrum herbicides used with herbicide-tolerant GM crops not only decimate wild species indiscriminately, but are toxic to animals. One of them, glufosinate, causes birth defects in mammals [13], A Swedish study now links the top-selling herbicide, glyphosate, to non-Hodgkin lymphoma [14]. GM crops with bt-toxins kill beneficial insects such as bees [15] and lacewings [16], and pollen from bt-maize is lethal to monarch butterflies [17].
8. A potential source of health hazards from GM crops is from the secondary horizontal transfer of transgenic DNA to unrelated species; in principle, to all species interacting with the transgenic plants [18]. The spread of antibiotic resistance marker genes to pathogens is the most immediate danger as this will further compromise treatment of life-threatening drug and antibiotic resistance diseases which have come back worldwide. However, the random insertion of foreign DNA into genomes associated with horizontal transfer of transgenic DNA can also result in many harmful effects, including cancer in mammalian cells [19]. The potential for horizontal gene transfer is now also acknowledged by sources within the US and UK Governments.
9. The possibility for naked or free DNA to be taken up by mammalian cells is explicitly mentioned in the US Food and Drug Administration (FDA) draft guidance to industry on antibiotic resistance marker genes [20]. In commenting on the FDA's document, the UK MAFF pointed out that transgenic DNA may be transferred not just by ingestion, but by contact with plant dust and air-borne pollen during farm work and food processing [21], and
cited several significant new findings bearing on the issue.
10. Thus, plant DNA is not readily degraded during most commercial food processing [22]. Procedures such as grinding and milling left grain DNA
largely intact, as did heat-treatment at 90°C. The DNA of plants placed in silage showed little degradation of DNA, and the special MAFF report advises against using ensilaged transgenic plants in animal feed.
11. The letter from UK MAFF to US FDA also mentions new findings that the human mouth contains bacteria capable of taking up and expressing naked DNA containing antibiotic resistance marker genes and similar transformable bacteria are also present in the respiratory tracts [23].
12. What both regulatory authorities have failed to consider is that transgenic pollens, which may have increased allergenicity and toxicity besides, will almost certainly spread far afield to the general public. Similarly, the current unregulated practice of feeding farm animals transgenic grain and plant remains, and transgenic wastes, both ensilaged and otherwise, is endangering the health of farm animals and of human beings in spreading antibiotic resistance marker genes and other transgenic DNA.
13. Serious health concerns are also raised by the cauliflower mosaic viral (CaMV) promoter in transgenic DNA. The CaMV promoter, widely used in expression cassettes of transgenes, is known to contain a 'recombination hotspot'. One usual mechanism of recombination involves the double-stranded DNA breaking and joining with other double-stranded DNA. This has been identified as the mechanism generating many different lines of transgenic rice during a routine transformation experiment. Extensive recombination at the hotspot has taken place in the absence of the viral recombinase, indicating that the host plant cell can catalyse such recombinations [24]. Thus, the CaMV promoter has an enhanced capability to transfer horizontally, with potentially dangerous consequences.
14. CaMV is closely related to human hepatitis B virus, and also has a reverse transcriptase gene related to that in retroviruses such as the AIDS-associated HIV [25]. Thus, the CaMV promoter not only enhances horizontal gene transfer, but has the potential to reactivate dormant viruses (which are in all genomes) and to generate new viruses by recombination.
15. The British Medical Association, in their interim report (published May, 1999), called for an indefinite moratorium on the releases of GMOs
pending further research on new allergies, the spread of antibiotic resistance genes and the effects of transgenic DNA. This position is fully in accord with the precautionary principle.
16. Contrary to the claims of the UK Government, no useful results can be obtained in the current massive 'farm-scale' trials of transgenic herbicide-tolerant oil-seed rape and maize where the spread of transgenic pollens cannot be controlled, and which make no attempts to monitor for horizontal gene transfer or for impacts on health [26].
17. Research into sustainable, non-corporate agricultural systems which do not involve GM crops should be widely supported. Many of these systems have already resulted in increased yield and income for family farmers, diminished environmental impacts, and improvements in nutrition and health for all [27].
