GMO - Genetically Modified Organisms
Genetically modified organisms (GMO) can be defined as organisms which DNA has been transformed by the insertion of one or more genes (trans-genes) in a way that doesn’t exist in the nature. These genes may be transferred from not related species: animal genes may be transferred to plants, bacteria genes to plants or human genes to animals. Living organisms that have been created in that way are able to mutate and reproduce.The subject of GMO in food and agriculture is highly controversial. Although, genetic modification is generally seen as a tool offering potential benefits to farmers and consumers in a wide range of food and agriculture areas, there is concern about the potential impacts on human health and on the environment. GMO is being brought into circulation because of its benefits for producers and consumers, that is: getting products with lower price, longer durability and higher nutrition content. The preliminary goal of researches on GMO was the improvement of the crops’ protection. Current GMO products on the food market are characterized by: improved resistance to diseases spread or caused by insects and viruses (insertion of genes which produce toxins descended from Bacillus thuringiensis bacteria), and
Besides the benefits and supporters, GM technology has also a lot of disadvantages and opponents. Benefits and dangers connected with GMO food can be considered in the following categories: The basic weakness of the GM technology is its imprecision. Scientists don’t posses the sufficient knowledge to modify the DNA without the risk of creating a mutation which may be harmful to the environment and to our health as well. The most concerns apply to: ability of spreading GMO and potential possibility of insertion of new genes into the living organisms, susceptibility of unintentional organisms (like insects which aren’t pests) to effect of genes, stability of the gene and limitation of biodiversity and increased used of chemicals in the agriculture. Scientists change the DNA of the products, but without long and precise researches we can’t determine whether the GM food is safe. Among the potential risks for the human’s health we can list:
