GENETICALLY MODIFIED FOOD

  For a couple decades,genetic science has been advancing.  These developments in genetic science offer us many things that vary from treating cancer to producing GMO foods.  GMO is an abbreviation of genetically modified organisms. It is a term which represents the human intervention into the genetic structure of the organisms by using advanced technology and specialized molecules. This intervention enables humanity to reduce pesticide usage, to grow nutrition rich products and more resistant plants. Besides these benefits, GMO has a dark side, too. Changing the genetic structure of plants negatively affects the non-targeted bugs and it also increases the resistance of weeds. For these reasons, GMO has both advantages and disadvantages.
  Firstly, GMO has numerous advantages. Some bacteria in nature make insects sick. The combination of different parts of the DNA from these bacteria which are called plasmids, is transplanted to the plant’s DNA. Harmful bugs get poisoned by new genes such as Bt. Thus, pesticide usage is being reduced day by day thanks to thetransplantation of genes. Moreover, GMO can increase both the nutrition level of foods and the amount  of food. Many people suffer from starvation due to numerous factors. Unfortunately, starvation causes many sicknesses owing to lack of vitamins, minerals, and proteins.More nutritious food is definitely a good thing.Therefore, science can help to figure out a couple of problems that are written above.
    Secondly, regrettably, GMO has some disadvantages that scientists are trying to solve. By transplanting bacterial DNA to plants, we sometimes kill the non-targeted bugs such as bees and butterflies. Killing non-targeted bugs negatively affects the food chain. This slaughtering of bugs may also harm plants because some bees and butterflies carry pollen. GMO might increase the resistance of weeds. Resistance is a consequence of evolution. The mechanism of evolution is based on natural selection. Natural selection means, when weak ones die, the strong ones which carry the resistant gene can live and reproduce.For this reason, off-spring of the new generation become more resistant.

  To conclude, GMO has both some advantages and disadvantages as many other things do. It can help us produce nutritionally rich food and decrease the level of pesticide usage. It can also result in more resistant plants and kill non-targeted bugs like bees. Despite all the negative perspectives, science can, surely, deal with these drawbacks and produce perfect food for every single person in the future.
