Beware of GMO Food Agriculture

By Lee Jacobs

GMO foods or "Genetically Modified Organisms" are the subject of high controversy. We seem to have been lulled into something of a state of complacency, because when GMO foods first hit the headlines, there was a general uproar. Today however, despite the ongoing progression to design more and more varieties of GMO foods, we seem to hear very little by way of protest. I am sure that we all understand the logic behind the theory, and that to some extent we agree. After all, in a world where the population continues to expand at an appalling rate, food supplies are under more and more pressure. If we can develop crops that can be brought to harvest more quickly and that are far more resistant to disease, pestilence and drought, it all sounds very positive. But at what cost?

Genetic engineering as a science, and as a practice, is now quite advanced. The big problem on many people's minds though is: "do we properly understand what effects tampering with the genetic make up of crops will have on the surrounding environment?" The concern is that the ecosystem is very complex and everything exists for a reason. What would happen, if by accident, and not fully understanding the ripple effects, we were in our ignorance, to take out, or modify, an important component that Mother Nature had put there for a specific purpose? It is almost impossible to say what sort of ecological mayhem this might cause in the fullness of time; it may not happen now, it could take several decades to "wash through".

Another important issue that has arisen due to the rise of GMO foods is that the crops that we can grow may very well become less genetically diverse. The more diversity that is present in the food that we eat, the better, and without this diversity, there is a much greater risk of seeing huge swathes of produce wiped out if they are confronted with a microorganism that they cannot deal with. Similarly, there is also the fact that due to the lessened diversity of the produce that is grown, the people who grow them are going to be become more dependent on chemical and biotech agents to protect them. What this means later on down the line is a increased presence of pesticides our food.

We are all familiar with the miracle of evolution. Plants and animals are in a constant process of evolution. It takes many decades and sometimes centuries for changes to be noticed, but they are going on all around us at this very moment in time. But if Mankind were to interfere with that process by putting in unnatural, dominant strains of crops, what will happen? One school of thought says that in time, Mother Nature will respond by developing a new super weed or pestilence to counteract this new dominant strain. There are several different scenarios that stem from here. One is that the new pestilence totally wipes out all of the new dominant strain of crop. Result? Potential starvation! Another theory is the development by Mankind of a super chemical agent to combat the pestilence. Result? (a) Once again we are introducing unwanted chemicals into the food chain, and/or, (b) we may cause another unprecedented and unimaginable ripple effect that causes further damage to the environment.

For the time being, we should halt any further development of GMO foods until such times as we fully understand all of the potential repercussions. - 17273
