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.
