Dangerous GMO’s!

The quest for global food security has over the years witnessed aggressive efforts to create plants that can withstand changing climatic conditions and plant diseases. The most prominent of these attempts is the creation of genetically modified organisms, popularly known by the acronym ‘GMO’. Fortunately or unfortunately, while this development is worthy celebrating, it is surrounded by serious controversy and inherent danger.

From the onset, it is important to state that GMOs are far from being safe as many would have us believe. But before we delve into the dangers of GMO, let us first understand what GMO is all about.

Understanding GMO

Let us begin from the known and proceed to the unknown. By nature, every organism has its unique composition, the DNA that differentiates it from others. A natural plant is one that has all its genes intact as it was created or as it has evolved over the years. In essence, natural corn, for example, should have all the qualities of corn as we have known it over the years.

Scientists, however, argue that as plants and animals continue to evolve, they undergo changes that may alter their chemical and nutritional composition. This is especially because soils continue to lose their fertility and plants cannot get all the nutrients they used to earlier. Animals feed on the deprived soil. Moreover, the use of fertilizers and chemicals means that the genetic makeup of the plant can be altered. The consequence is that the plants we know today are of lower nutritional value than before.

It is also argued by experts that plant diseases and pests have over the years lowered the quality of plants and other organisms thus the need for mechanisms to prevent the harmful effects of these diseases. Unless these diseases are prevented from affecting and destroying organisms, some plant and animal species will disappear soon. These and other reasons are used to front GMOs.

A GMO is an organism that has had its genetic composition interfered with through artificial means especially in a laboratory. Through a process called genetic engineering, scientists extract the DNA of one type of plant or animal and replace the removed material with others from sources that have no relationship with the original organism.

The sources of new genes are often other animals, plants, insects, viruses, bacteria or even animal tissue. It is important to remember that this is contrary to the natural way in which crossbreeding among species occurs. Next time you come across the term ‘transgenic’ organisms, you need to realize it has the same meaning as GMO since it denotes the transfer of genes between different organisms.

When this is done, the plant has to change in terms of its nutritional and chemical composition and in some cases the physical appearance. Moreover, and more importantly, genetic engineering not only alters the genetic infrastructure of an organism, but is also unpredictable and extremely mutative. Moreover, allergic reactions and toxins often follow genetic engineering.

We also need to realize that in the past there have been other attempts to improve the quality of species. These include tissue culture, selective breeding and hybridization. The difference between these traditional genetic methods of gene improvement and genetic engineering is that the former actually aids nature instead of circumventing it.

The other complication is that genetic engineering may actually act contrary to the ideals of improving the genetic quality of organisms. For example, some crops return lower yields after genetic engineering. The same happens with nutritional value. Allergic reactions and toxicity are attendant problems, but even more worrying is environmental degradation stemming from GMOs.

GMO research was at first perceived to be for research purposes only, but with time, it became clear that there were commercial interests. Today, many food crops have been genetically modified to some extent. We are talking of papaya, soybeans, corn and other plants such as cotton. Despite this, most of the food we eat remains natural and this includes rice, oats, where, tomatoes, beans, grapes and barley.

In relation to animals, there are no GMO creatures at this time. Well, there was an unsuccessful attempt to create GMO pigs, but it was shelved after a short trial. However, the fact that animals feed on GMO corn and soy means that the negative impacts of GMO will affect people who feed on such animals. The fact that GMO foods are not clearly labelled puts everybody at risk.

Why, should you be concerned?

It would be unfair not to underline that research on the harmful effects of GMOs is on-going. However, it is important to note that there are regions that have adopted a wait-and-see attitude instead of rushing to adopt GMOs. For example, in the EU, GMOs crops are rarely grown and any GMO products must be clearly labelled to help a buyer to make a personal decision on whether to consume such products or not.

Secondly, some scientists have expressed reservations to GMOs on the basis that the allergies witnessed during genetic engineering might affect consumers. This is a genuine concern considering the prevalence of diseases such as cancer, which primarily involve irregular multiplication of body cells. One wonders, then, whether it is necessary to eat GMO food when there are natural alternatives.

Another concern related to GMOs is that the entire process eventually harms the environment. This is especially true in relation to GMO farming. Pesticides are the main issue here. Companies that manufacture GE seeds are also the main producers of pesticides. While GE seeds are made to withstand herbicides, farmers must purchase chemicals to kill weeds. The problem is that farms develop weeds that resist chemicals in the long run thus requiring even more harmful insecticides.

It is obvious that when the environment is harmed by chemicals, human beings will suffer. Polluted air, soil and water in turn contribute to death of marine life, global warming, toxicity in water sources, death of plant and animal life and the plethora of illnesses that we are battling today. In essence, we can suffer direct and indirect consequences of developing, nurturing and consuming GMOs.

What should we do?

As intimated earlier, it is imperative that we ask ourselves whether we really need GMOs. Nature is resilient and altering its cause can only results in disaster in the long run. Global warming and its consequences are clear evidences of that fact. Before you introduce GMOs in your diet, ask yourself whether you have exhausted all existing natural alternatives.

We must start reading labels on the food materials we buy and ensure we don’t form a habit of constant consumption of GMOs. It is important to be careful when we buy canola, alfalfa, papaya, corn, soy, and sugar beets. These are foods that have undergone extensive genetic engineering. Some, like, soy, are totally transformed from what we were used to.

We need also to ask ourselves whether GMOs are manufactured for the benefit of humanity or the firms than create them. Why is it that the largest manufacturers of GE foods are also the leading makers of chemicals to fight weeds? Are we helping businesspeople to make more money at our expense or we really need GMOs for survival of the human race?
