GM food, otherwise known as genetically modified food, some say it's safe, some say it's hazardous. Mysterious to many and a staple to others. Supposedly highly sought after by farmers. So what really is GM food? Does GM food harm or help people?
Well let us speak about what GM food is and how it's made. GM foods are food products genetically modified to have certain traits. An example of such a food is seedless grapes, for the convenience of people who do not wish to deal with the numerous seeds from the grapes. So as we can tell, these traits differ from what is the norm of these food products when found in nature. Most people think that only food products from plant sources can be genetically modified, however this is very incorrect. Meats are most likely genetically modified. Such as in salmon that are modified to be larger and stronger than usual in the wild to increase yield of salmon products in aquaculture. It sounds extremely profitable to farmers to have a improved version of everything right? Well GM food does have its drawbacks to farmers as well. Notice how GM food, especially plant products, are significantly more pricey than normal products? Well this is because companies selling seeds of GM food tend to disallow reproduction of the plant. This is for the need of farmers to constantly buy seeds so that the company earns more profit. So what good has GM food brought to humans? Well there is a famous example that testifies the power of GM food and that is the Golden Rice Project ran by the Golden Rice Humanitarian Board. Golden rice is a genetically modified version of rice that, as the name suggests, is gold in colour and is packed full of Vitamin-A. The Golden Rice Project was originally started to combat night-blindness, a Vitamin-A deficiency, commonly occurring amongst less developed countries where access to fresh and nutritious food is scarce. With golden rice, this staple food satisfies the necessary Vitamin-A daily intake and has been a phenomenal innovation by the biotech industry and prevents about a third of all under-five deaths, which amounts to up to 2.7 million children that could be saved from dying unnecessarily. Now time to answer the question that everyone wants to know, is GM food harmful or not? Well the answer is yes and no. Towards us humans, GM food is generally safe and is approved by the FDA ( Food and Drug Administration). In some rare cases, some people may develop certain allergies. Towards the environment however, GM Food is extremely harmful. Genetically modified plants such as pest resistant vegetables can cause the decline of certain pests in an area. This doesn't sound so bad, heck it even sounds great. However, this is extremely bad to the environment. Some predators may rely heavily on this pest and killing it off may destroy the balance in the ecosystem. A simple example of this can be represented in a simple food chain as represented below. Maize/Corn -> Corn Borer (Maize-eating worm) -> Birds Now to put it simply, the bird populations will dwindle down. Why? Well the birds rely on the corn borers for food but when GM Corn is introduced, the corn will contain Bt proteins, a toxin to the corn borer, hence killing the corn borer, reducing the amount of food sources for the birds. Another problem is the possibility of the corn borers gaining a resistance against Bt, hence giving rise to a generation of unstoppable corn borers. Now let us look at the same food chain that is slightly different. Maize/Corn (Nectar) -> Monarch Butterfly Now this is where it gets interesting. Some of ya'll may think so what? This isn't affecting humans. Well it does here. With the nectar of the maize now being toxic to the butterfly, the maize will not be able to be pollinate. You see, as the butterfly goes on the flower of the maize to drink nectar, the pollen falls on the butterfly. As the butterfly travels to other maize flowers, the pollen from the butterfly falls onto the new flower. This is known as cross-pollination. Without pollination, the flowers will never be able to turn into corns which are the crops we humans want. Maize being a staple to most countries of the US, GM crops may destroy the US food export economy and food supply of maize. This is just one of the many examples of GM crops and its impact on the environment, many more examples are out there. From this all, we can conclude that GM food has no harm onto humans, in fact it has brought us alot of good. GM food however, harms the environment and can cause a lack of biodiversity. Now it's up to you to decide if you support GM food or not.
