1. Genetic Modification Versus Hybridization
Is there a difference between the two?Genetic modification is a deliberate alteration of an organism’s genome. By inserting the genes of one or more species into the genes of another through a modern genetic recombination technique (also called DNA recombination technique), a brand-new variety is produced.
Hybridization, on the other hand, is a practice of thousands of years that cross-pollinates two species to create a new one in a completely natural process. The process can then be cultivated over time for a desired outcome. Hybridization also occurs naturally in nature—no humans needed.
2. The Purpose of Genetic Modification
What is genetic modification used for? There are three official answers.- Increased production of food. It is said that around 820 million people are living below the hunger line and that increasing the yield of food has become the foremost reason for using genetically modified organisms.
- Improved nutritional value of food. In the process of plant genetic modification, foods can be modified to increase the content of protein, vitamins, and trace elements.
- Increase plants’ tolerance to herbicides and insecticides. In addition to providing weed and insect control, genetic modification strengthens plants’ ability to withstand large amounts of chemical herbicides and pesticides that otherwise could render plants unhealthy.
3. The Controversy Around GM Food
Why are genetically modified foods so controversial?- There are other ways to improve food production levels. Agricultural experts believe that genetic modification is not the only way to improve yields. Good soil, proper cultivation methods, and practices such as crop rotation can all increase yields.
- Evolution of new food sensitivities or allergies. GM-led transgenics, while attempting to provide increased nutrition may also give rise to new allergens. For example, increased methionine in soybeans, due to genetic modification, may cause allergies in some people.
- Stronger pesticides can create stronger pests. Proponents of GM soybeans argue that GM plants require fewer herbicides and fewer pesticides to grow. However, challengers argue that the results of genetically modified plants could lead to the evolution of new superbugs and weeds. As plants naturally evolve to thrive in ever-changing environments—as do insects and weeds.
4. An Experiment on the Safety of GM food
Of most concern is whether genetically modified foods are of any harm to human beings. Due to the relative newness of GM foods, there are not enough long-term observations from studies of human consumption of GM foods to make a definite conclusion.However, the jury is still out. The transgenics study was performed on rats—not on humans and the research period was only 90 days. Other experiments on animals have also been performed that indicate that genetically modified foods can increase people’s risk of cancer and autoimmune diseases. Thus, the debates are bound to continue.
Genetically modified foods are different from naturally grown ones in terms of the ways they are cultivated. We should respect nature, and use natural methods to produce enough healthy food based on human wisdom.
