Genetic Modification technologies are neither good nor bad, they are tools. Anyone can agree with this, including activists and Monsanto.
Can GMOs be bad? They certainly can, for simple logical reasons. When a genetic modification is introduced, the resulting organism is different by definition. The differences may be small or large, visible at first sight or after microscopic investigation only, immediate or delayed; they may relate to the shape, chemical composition or biological properties (such as resistance of reproduction) of the resulting organism. A GMO may therefore carry or produce toxins, hormones, proteins which were absent from the natural organism. Their presence may induce, on the short or longer term, allergies, epidemics, all of which may also be extended and multiplied by genetic alterations all over the food chain, as well as by contamination of other cultures.
It is therefore a logical property of Genetic Modification technologies to induce a high level of risks. Theoretically, risks of the same kind are also present in the random natural modifications described by the theory of evolution. They exist, however, at a much higher order of magnitude in GMOs, as modifications occur and spread at a completely different pace and on a totally different scale. Traditional graft hybrids were unable to affect most aspects of the DNA and definitely did not cross the animal/vegetal-barrier, generating moderate biological risks. It should also be noted that graft hybrids increased biodiversity, when GMOs now tend to reduce it, because of the existence of specific ‘kill-all non GMOs’ pesticides (namely the ‘RoundUp’), as well as for economic reasons.
Now that we have the certitude that Genetic Modification technologies can induce dangerous biological consequences on a very large scale, the only question becomes: how should we handle them?
Industrial GMOs appeared in the 90’s, during the peak of the Great Deregulation move. Instead of being submitted to at least the same control than pharmaceutical products, or even the same than mere food additives, they benefited from an extraordinary political decision in the U.S. It was legally decided (not scientifically established, which would have been impossible) that a ‘substantial equivalence’ existed between them and natural organisms. The meaning of this decision, which is still in force, is that no evidence of their innocuousness has to be established by their producer, under the control of independent public agencies like the FDA, before they are put on the market. Moreover GMOs should not be tagged as different for the consumer who thus becomes the unwilling guinea-pig of a free and large scale experiment from which no one can opt out.
In practice, free trade agreements do not allow any country to decide in favor of more reasonable precautions. The maximum limit to GMOs is the possibility to tag them locally or suspend their distribution when and only when positive evidence of their actual dangers can be legally set forth. As even complete bans could not protect entirely other crops from contamination (which already happened in the case of the Mexican maize), any shorter measure represents a superior level of risk.
The advantages of GMOs would deserve a specific discussion. Let’s say briefly that they are unclear. They probably can increase the productivity of certain crops, prolong the delay of conservation of fresh products, improve the visual quality or even the taste of insipid industrial food, and they certainly can increase the profits of Monsanto. This is well enough to build up strong lobbies in their favor. On the other hand, they cannot eliminate or even reduce the need for pesticides. They increase the cost of seeds now submitted to a growing monopoly. They tend to eliminate agricultural independence of other countries. It is also interesting to note that the generalization of GMOs preceded a spectacular surge in the price of agricultural commodities, particularly those, like soy, in which their market share is the largest. Once these macroeconomic downsides and the biological risks described above are put together, the cost/advantage balance seems to go clearly at this stage against the GMOs.
One would like to review more scientific literature on such a major topic. It unfortunately turns out that most of the relevant research is directly or indirectly funded by Monsanto, and should be considered as unreliable at best, a situation which in turn increases the level of incertitude and risk.
The problem is that no matter how powerful lobby is, it cannot resolve the issues it so actively keeps hiding. No matter how blind a government is, when pushing across all borders a potentially very dangerous type of product for a short-term trade-balance advantage, it cannot prevent disasters to occur. Innovation does not imply letting irreversible problems take place before we learn how to take them under control.
GMOs may have a brilliant future once we know how to handle them. This is not the case yet. Even though genetically induced pandemias have been avoided during their very recent industrial devolopement, biological and economic incidents have already taken place, from mass suicides of Indian peasants, to accidental contamination of crops and allergies to associated pesticides. Time has come for independent research, limited experiment, premarket control, not yet to wild and world-scale industrial applications. The exact opposite is happening.
This is how the world goes.
