The GMO Debate: Part 1

Fitday Editor

GMO stands for "genetically-modified organisms" which basically refers to plants that are created by using the latest biologic techniques for human and animal food consumption. This used to be done by conventional plant-breeding methods but that is very time consuming and not always accurate. Genetic engineering can create plants exactly the way we would like them with much greater speed and accuracy, plus they are resistant to herbicides and their nutrition content has been improved.

Advantages of GMOs

Reduced Pesticide Use

Farmers spend tons of money on pesticides to keep their crops from being eaten by insects but most people do not want to eat food that is covered in chemicals. GMOs like corn, for example, could be grown without pesticides which would save costs to farmers in bringing a crop to market.

Crops Resistant to Weed Killer

Instead of removing weeds by tilling the soil, farmers often spray large quantities of weed killer to destroy weeds which is a very expensive process that requires quite a bit of time and effort to prevent the weed killer from harming the crops and the environment. Crops can be genetically engineered to be resistant to weeds so only one application of weed killer would be necessary, limiting the costs and dangers of excess run-off.

Crops Resistant to Disease

There are many viruses, fungi and bacteria that cause plant diseases. Plant biologists are working to create plants with genetically-engineered resistance to these diseases.

The Disadvantages of GMOs

Harm to Other Crops and Species

For example, a study published in Nature magazine showed that pollen from GM corn caused a high death rate among Monarch butterfly caterpillars. Monarch caterpillars eat milkweed plants, not corn, but the fear is the pollen from the GM corn could be carried to other fields through the wind where the caterpillars could eat the pollen and die. There is agreement that this study must be evaluated further but there is concern on both sides of the issue.

What Is the Solution?

There are several possible solutions to the problems mentioned above. Genes are exchanged between plants via pollen so there are two ways to ensure that non-target species will not receive introduced genes from GM plants. One way is to create GM plants that are male sterile (do not produce pollen) or to modify the GM plant so that the pollen does not contain the introduced gene. Cross-pollination would not occur, and if harmless insects such as monarch caterpillars were to eat pollen from GM plants, the caterpillars would survive.

Other Health Risks

There are many children throughout the United States and Europe who have developed allergies to peanuts and other foods which are life-threatening. The possibility of introducing a gene into a plant might create more allergic reactions or create a new allergen altogether so labeling of GMO foods is critical in more ways than one.
