Genetically engineered foods have attracted a large amount of media attention in recent years and continue to do so. Despite this, the general public remains largely unaware of what genetically engineered foods actually is or what advantages and disadvantages the technology has to offer.Two main areas of concern have emerged, namely risk to the environment and risk to human health.And I think that genetically engineered foods should be boycotted by restaurant owners, supermarket owners, consumers in general in order to eliminate this potential danger.
Firstly, the genetically engineered foods may do harm to individuals and the animals. For example, some genetically engineered crops’ gene is transferred from other plants which are quite different, and this makes them resistant to insects. Since this special crop are resistant to insects, they may be also poisonous to certain animals, and even people. It can affect other species through genetic drift, threat to the biodiversity. Secondly, there is a potential danger. Many children in the US and Europe have developed life-threatening allergies to peanuts and other foods. There is a possibility
that introducing a gene into a plant may create a new allergen or cause an allergic reaction in susceptible individuals. There is a growing concern that introducing foreign genes into food plants may have an unexpected and negative impact on human health. A recent article examined the effects of genetically engineered potatoes on the digestive tract in rats. This study claimed that there were appreciable differences in the intestines of rats fed genetically engineered potatoes and rats fed unmodified potatoes.
There must be more disadvantages responsible for what I suggest. So for the sake of the ecosystem and our safety, the genetically engineered foods should be abandoned.And we must proceed with caution to avoid causing unintended harm to human health and the environment as a result of our enthusiasm for this powerful technology.
