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.
Topic: Should more be done to protect against natural disaster?
POINTS： ●Evacuation ●Research funding ●Technology ●Prediction ●Cooperation between industry and academia ●International cooperation
In recent years, the world has experienced a series of truly devastating natural disasters that have taken many lives and triggered unprecedented economic losses. These events:earthquake in Japan, Hurricane in the United States, have demonstrated that even the most wealth and well prepared countries can see large-scale damage and destruction when natural disasters strike.At this point, it is doubtful that the protection against natural hazards is enough.
What is required of today's meteorological industry is precise prediction by utilizing technology.With the global spread of mobile phone and networks, this technology is now increasingly used for data correction of weather by individuals.Therefore, experts can predict clearly localized downpour and other climate anomalies.
International corporation is a need of improvement for these systems. There is a huge gap between developed countries and emerging countries in predicting and protecting from natural disasters financially and technologically. The sheer volume of data from all over the world can reduce casualty by making people evacuate when these events hit.
In conclusion, it is evident that we are not well prepared for rare extreme events. These systems are not still working properly.People's awareness and education are not sufficient.Therefore, more protection is necessary for reducing risk against natural disaster.
