Chapter 1003 The Pros and Cons of Transgenic Technology (Supplementary)

In addition, in terms of ecology, if the relevant genes of transgenic crops are transferred to relative wild species, it will pollute the entire gene pool of seed resources, thereby changing regional plant genes, or even global plant genes, which will cause great harm to the ecological environment .

Moreover, humans are also a part of the natural ecosystem, and people worry that these genetically modified plants may also endanger the genes of some animals that have been fed with plants, and eventually affect human genes.

Take the Pustai incident as an example. In the autumn of 1998, Pustai of the Rowett Research Institute in Scotland gave a speech on TV, claiming that he fed rats with potatoes transmuted with snowdrop lectin gene. The system is compromised."

The transgenic canola super weed event in Canada. In 1995, Canada first commercially planted genetically engineered rapeseed.

However, within a few years after planting, it was found that individual rapeseed plants could resist 1 to 3 herbicides in the rapeseed field, and some people called it a "super weed". Later, after investigation, it was found that the reason for the generation of this kind of rape plant was that when the farmers harvested the transgenic rapeseed seeds, some of them were left in the field. caused by genetic drift.

In 1999, the authoritative scientific journal "Nature" published a paper by John Rossi, a professor at Cornell University in the United States, pointing out that butterfly larvae and other field beneficial insects would stunt and die after eating vegetable leaves sprinkled with certain genetically modified corn pollen rate is particularly high.

There are quite a few similar incidents. Although some incidents were later officially misreported, they did not alleviate people's worries about genetically modified technology and genetically modified crops, but aggravated the sense of mistrust.

It is believed that since these genetically modified plants can affect other crops and even animals, when humans come into contact with and use these genetically modified plants or plants, livestock and poultry contaminated by genetically modified animals and plants, it is very likely that human genes will also be polluted. Thereby producing some diseases, causing harm to the human body.

In addition, genetic technology uses antimicrobial resistance genes to identify genetically modified crops. After genetic food enters the human body, it may affect the efficacy of antibiotics on the human body, and mutated genes in crops may cause new diseases.

The protein transfer in the transgenic technology may cause the human body to be allergic to the food that is not allergic to it. Whether the new protein traits after segmentation and recombination fully meet the needs we imagine needs to be studied to demonstrate its safety.

There is also the artificial extraction and addition of genes, which may increase and accumulate the original trace toxins in food, and unforeseen biological mutations will increase the level of original toxins or produce new toxins.

Even for the ecosystem, genetically modified food is an intervention on a specific species to artificially gain a competitive advantage in the living environment, which will inevitably destroy the natural law of survival and cause changes in the ecological balance.

Moreover, it is impossible to preserve or restore geneticized organisms, bacteria, viruses, etc. entering the environment, which is more serious than chemical or nuclear pollution, and the damage is even more irreversible.

Although people's worries about genetically modified technology have not been eliminated, in fact, genetically modified crops have quietly entered our lives.

It is very likely that some of the raw materials we buy contain genetically modified raw materials. And among those non-GMO agricultural products marked on the market, how many are real and how many are fake?

Of course, you don't have to worry too much. Judging from the current series of research reports, genetically modified technology and some genetically modified crops currently on the market are safe, and will not cause marketing or harm to people.

And many international organizations, such as the World Health Organization (WHO), the Organization for Economic Cooperation and Development (OECD), the World Health Organization (WHO), the Food and Agriculture Organization of the United Nations (FAO), the International Scientific Council, the European Commission, etc. International and regional organizations They all said that it has not been shown that the consumption of genetically modified food by the general public in countries that have approved genetically modified food has had any impact on human health. All genetically modified foods currently on the market are safe and can be eaten with confidence.

From the perspective of the world's development environment, even though genetically modified technology may have some negative effects, it is still not worth mentioning compared to the positive effects it brings and the huge achievements it has made.

After all, there are still tens of millions of people in the world who are below the hunger line, and more than a billion people have a single type of food and lack of nutrition, resulting in severe stunting.

So if this genetically modified technology can help these people get rid of hunger, achieve food and clothing, help those people achieve food diversification, enhance nutrition, and promote development.

Even if there are some risks, it is worth promoting vigorously.

However, in developed countries, they are still cautious about this kind of genetically modified technology and the related animals, plants and crops used by genetically modified technology.

And our country has very strict control over this area, and related experimental planting needs to be applied for. Proceed only after approval has been obtained. Otherwise, severe penalties will be imposed.

For example, someone once privately planted dozens of acres of genetically modified corn. After being seized by the local authorities, the dozens of acres of genetically modified corn were immediately pushed away, and all the immature genetically modified corn stalks were collected for burial and incineration.

In addition, the parties involved were also detained and fined locally.

Therefore, even various research institutes need to apply when conducting related genetically modified technology experiments.

For example, this new type of genetically modified Haloxylon tree, in the next step, Yang Fang and the others will plant it outdoors on a certain scale. On the one hand, it is to test the stability of the new transgenic Haloxylon tree gene, and on the other hand, it is to test the performance of the new transgenic Haloxylon tree in the natural environment and its adaptability to the harsh natural environment.

In addition to this new type of genetically modified Haloxylon tree, there is also the 100-acre rose garden promised by Yang Fang to Wu Hao, which also needs to be applied for. Because the genetically modified roses that Yang Fang and the others bred are also genetically modified crops, which need to be strictly controlled.

And in accordance with relevant requirements, these genetically modified plants used in experiments must be strictly supervised to prevent leakage of their provenance. And it is required that the related flowering plants, that is, the seed plants, be removed and cleaned before the seeds mature, or be reliably protected to avoid the outflow of seeds and the impact on the surrounding natural ecological environment.

This is just an official attitude. In the civil society, because of the unremitting efforts of some long-term fighters against genetic technology, the folks regard genetically modified technology and genetically modified plants as a scourge and avoid them.

Therefore, I am afraid there is still a long way to go before the domestic public can accept this new type of genetically modified plant, let alone large-scale planting and application.
