2009年度第1回(2009年6月実施) TOPIC：Do the benefits of genetically modified crops outweigh the dangers?
● Economic impact ●Global warming ●Government regulations ●Human health ●Resistance to disease and pests ●World hunger
Not uncommon today is the label of "This product is not used genetically modified crops" on daily seasonings at the supermarkets. Finally mutant salmon, which is genetically modified huge salmon, has been on the market- historic first aside from agriculture industry.All for its presence today, little is know about its potential danger.
First reason is associated with human health. Many experts alarm that continuous consumption of GM crops may cause serious diseases: cancer, leukemia, and allergy. This is demonstrated by animal tests, and some mice had a huge malignant tumor.
In addition, this biotechnology can build up resistance to some diseases and pests in crops. This indicates the less pests there are, the less beneficial insects.Nearly a third of the honeybee population has been wiped out since 2006 because of herbicide which related to GM farmers. Moreover, GM seeds cross breeding with conventional seeds. There is the potential of irrevocably damage in the environment, which brings out a negative economic impact on nations.
Finally, since GMO is expensive, availability is limited. It is too costly to cultivate these crops for general farmers. Therefore this ends up widening the earnings differentials between rich and poor cultivators. In the different light, consumer are reluctant to buy these products out of concern about negative effects.
In conclusion, I doubt that the benefits of genetically modified crops outweigh the dangers. Many scientific evidence show that this technology is unacceptable. More researches should be done to prove the safety of GMO.
