Genetically modified foods have long been on the table, and the concern about the safety of genetically modified organisms has long been unsustainable. At the Bio-industry Conference held yesterday at the Bio-Agriculture and Green Food Forum, experts dispelled the public’s concerns about the safety of genetically modified foods one by one, and called for accelerating the industrialization of genetically modified technologies and seizing the strategic opportunity for development.
GM safety standards and international standards
Yesterday’s forum, GM technology became the subject of experts’ speeches, and it was also a hot spot for the audience.
Is food safety caused by genetically modified crops insecure? Will it affect human health? Will it cause bizarre events like the Hollywood movie shows? In response to rumors of GM corn in rats in Shanxi and parts of Jilin, and stillborn sows, Wan Jianmin, director of the Institute of Crop Science at the Chinese Academy of Agricultural Sciences, said that according to their special investigations, the phenomenon was caused by the anti-rodent action and genetically modified corn was pure. The beggar was desecrated.
Regarding the Americans' argument that they do not eat genetically modified foods, Huang Dazhao, a researcher at the Institute of Biotechnology of the Chinese Academy of Agricultural Sciences, exclaimed "No" with detailed research materials. As early as 16 years ago, the United States approved the commercial cultivation of transgenic insect-resistant maize and herbicide-tolerant soybeans. The planted area now accounts for 86% and 93% of the total area of ​​corn and soybeans respectively. According to the statistics of the American Soybean Association, 2009-2010 total soybean production was 91.42 million tons, and domestic consumption was 48.03 million tons. It was mainly used for processing feed soybean meal and edible oil. The sales volume of edible oil reached 7.76 million tons, and the per capita amount was as high as 28 kg. . In Europe, 75% of corn and 60% of soybeans come from the United States, Brazil, and Argentina.
Huang Dazhao said that the development of safety issues in genetically modified technology is of utmost importance. In 1996, the Ministry of Agriculture promulgated relevant regulations, and since then it has risen to the State Council's laws and regulations, has achieved international connection, and has been strictly implemented in scientific review and administrative approval. For example, the scientific evaluation of GM rice research was done for 11 years. It was not until 2009 that a certificate was issued. The standard is stricter than international requirements.
29 countries planted GM crops last year
Global development of GM crops is strong. According to authoritative information provided by experts, in 2010, the global acreage of genetically modified crops reached 148 million hectares, which was 87 times that of 1996, with an average annual increase of nearly 5 times in 15 years. In 1996, there were only 6 countries that planted GM crops in the world and 29 in 2010. The planting area of ​​the four major GM crops also reached new heights. Four-fifths (81%) of the global soybean area, two-thirds (64%) of the cotton area, one-third of the corn area (29%), and a quarter (23%) of the area of ​​the rape planted All are genetically modified varieties.
Although nearly 40 countries and regions around the world have not formally approved the commercial cultivation of GM crops, they are allowed to conduct pilot studies or import GM crop raw materials for feed and food processing. In 2010, eight EU member states approved the planting of genetically modified crops such as insect-resistant maize; the EU Biosafety Commission announced that countries can decide whether or not to plant genetically modified crops; Sweden first approved the cultivation of transgenic high-quality starch potatoes. In 2008, the total revenue of global GM crop products exceeded US$130 billion, of which 70% was owned by multinational corporations.
The overall strength of China's transgenic breeding is far behind that of developed countries, and the capacity for independent innovation needs to be further improved. However, at present, some aspects of cotton, corn, and rice transgenic technology are among the most advanced in the world.
Transgenic breeding development at a critical time
According to Wan Jianmin, China's arable land area is two-thirds of that of the United States, but the amount of chemical fertilizer used every year is twice that of the United States; the amount of pesticide used is three times that of the United States, and it seriously pollutes the environment. At the same time, water resources and energy are also seriously deficient. Solving these problems requires increasing crop yields, and transgenic technology is an effective choice.
"If China can make full use of certain advantages in systems, resources, talents, and technology, seizing the favorable opportunity for the development of new varieties of genetically modified crops and vigorously promoting its industrialization will certainly enhance the international competitiveness of China's genetically modified technology and drive genetic breeding. The overall level has been improved to realize the leap-forward development of emerging agricultural industries such as genetically modified food, feed, and fiber.†Huang Dazhao bluntly warned that if we hesitate or even stop, not only will agricultural development be controlled by people, it will also give economic and social development to China. Bring serious effects.
Steel Wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Steel Wire Rod is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number.
