ผมเห็นว่ามีประโยชน์ดีเหมือนกัน ก็เลยเอามา post ด้วยเลย พรุ่งนี้จะเรียนครั้งสุดท้ายแล้ว (ยากมากเลย เฮ้อ..)
Genetically modified (GM) food is food that has been inserted some specific genes from other plants or animals to make it has some good characteristic. There are several aspects about the impact of GM food: environment, health and economy.
According to the lecturer, GM food ruins the ecosystem by this situation; when wind blows through GM farm and transfers some GM pollens to other crops, may be weeds. This could create superweed, the weed that is pretty hard to eradicate. It can be worse than that, in the case of large number of monarch butterflies which has been killed because of cross pollination. However, the writer suggests ideas in on the other side by statesing that GM food can provide the environmental profit by decreasing demand of poisonous pesticide and synthetic fertilizers so that can to help reducinge greenhouse gases.
In health aspect, the lecturer says that GM food creates new types of allergies. For example, some people who are allergic to peanut could be also allergic to soybeans that are inserted in which peanut’s gene is inserted in. In contrast, the passage states that GM food is profitable to health in vary various ways such as to improve nutritional content and to contain vaccines to heal some severe diseases.
For economic view, the writer also states that the GM’s techniques could yield higher production because GM food has resistance to drought, salinity, pests, herbicides and tolerance long shipping times. In the next 50 years, the world’s population will be double itself; GM food meets can meet this large amount of demand of food. On the other hand, the lecturers disagrees with this idea. He says that GM food will eventually give terrible impact to the economy because the companies which have invested a number large amount of money for GM research and development GM food would never sell GM seed in low prices. then The farmers cannot afford it which in turn to widen gap between the rich and the poor.
