• This kind of discussion in a short time is not easy to draw a conclusion. The controversy on GM crops should be said is a normal phenomenon. The first is the development of new breed itself is not perfect, the environment and human body in longterm impact is yet to be seen, people expressed concern is justified. Secondly, there are always some consciousness conservative people for new technology products are not accustomed to, refuse to accept. There is also affected by the trade conflict of interest, some governments and interest groups in the use of genetically modified food is not perfect enough and large trade war, to complicate things.
The European Union in April last year to suspend approval of new genetically modified agricultural products on the market, make a decision to suspend further again this year, transgenic crops planting and sale of. A voluntary planting of genetically modified crops farmers affected by other farmers protest, planting crops often destroyed. In late August this year after a period of time, the French farmers to fruits and vegetables, and even cattle manure dumped in some fast food shops in front of Macdonald, protesting the sale of beef bread and potatoes contain genetically modified food. The United States believes European action than " banana war" and " beef war" is more serious, threatened to take revenge.
Life science industry development is thing of nearly 20 years, because of its gestates tremendous hope is getting more and more attention. The western countries in 1990 has not yet been formally planted genetically engineered crops, to cultivate an area to already amounted to 40000000 hectare 1999. The world of transgenic seeds sales of $75000000 in 1995, while 1998 has surged to $1500000000.
Safety assessment:
For the safety of genetically modified food on international at present, no unified view, arguments should focus on GM food will produce toxins, whether through DNA protein hypersensitivity reactions, whether the effects of antibiotic resistance etc..
Defect:
1. may cause damage to the butterflies and other insects.
2. may affect the surrounding plants.
3. may keep insects or pathogen in the evolution of increased resistance, or the creation of a new species, after the same may harm crops.
Genetically modified food safety ቤተ መጻሕፍቲ ባይዱhat
Frankenstein is a British writer Mary Shelley's 1918 novel in physiology researcher, he was finally created their own monster to destroy. Now the Europeans to genetically modified crops for food called " Frankenstein foods ", means that the transgenic plants will cause an ecological disaster, threatens the existence of mankind. This metaphor is exaggerated, but their concerns are not entirely without reason.
Opposition to genetically modified food person deals with a wide variety of interest groups, from Greenpeace to farmers association to the Christian Church and so on, their objections centered on three aspects: First, GM is contrary to nature, so it is harmful. Supporters retort that, nowadays, a variety of crops is the original varieties, otherwise people eat vegetables on with the animal to eat grass. second, the plant is introduced herbicide or toxic pest functional genes, they provide the foods on the human body is safe? On this point, support the school emphasizes, so far there is no qualified research institutions found that genetically modified food harmful to human health evidence, but their long-term effects can only make inference, it is difficult to obtain the evidence to convince the people round.

Advantages
1. solve food shortage problem. 2 reduced pesticide use, avoiding environment pollution. 3 save production costs, lower food prices.
4 increase in food and nutrition, improve added value.
5 increase in food, improve food quality. 6 promotes the production efficiency, drive relevant industry development.
Third, too hurry to promote transgenic plants may affect agriculture and ecological environment? Promotion of Transgenic Herbicide resistant crops may encourage farmer excessive use of herbicides, so that some of the main crop damage or even extinction. Many farmers in developing countries has been to this class of main crops as a food supplement or as feed. The United States Fish and wild animal management department has been found in 74 plant species and endangered by herbicide. In addition, transgenic technology has the potential to cause biological pollution. Some Biotech Corp in order to protect their intellectual property rights, to sell a farmer the transgenic seeds made the " sterilization " processing. Indiana University Department of biology professor Martha Crouch's research shows that, the sterilization genes may inadvertently make other crops also became sterile
But on the other hand, although the country has grown to more than 4500 kinds of transgenic plants, but the government approval of species listed only 40, not 1%. This shows that governments are still cautious, technical factors, and ecological health and social ethics and other factors need to be weighed.
