Are genetically modified foods good or bad for humans?

Now there is controversy, some say there are hidden dangers, others say safety.

Who knows, I'm afraid I'll get sick while eating.

What are the disadvantages of genetically modified food, the following is for you to answer.

Genetically modified food is the use of modern molecular biotechnology to transfer the genes of certain organisms (animals, plants or microorganisms) into other species, and change some shapes of organisms through the modification of biological genes, so as to obtain food that meets human requirements.

The world's first genetic food was the genetically modified late-maturing tomato, which was put on the US market in 1993 and was successfully developed in 1983. Whether it is directly eating genetically modified food or eating food containing genetically modified ingredients, it is the consumption of genetically modified food.

Change the environment. In the process of planting and growing, genetically modified foods are still different from non-genetically modified crops, which will have a certain impact on the soil and the surrounding ecological environment, and this impact is not necessarily positive.

Pest upgrades. Genetically modified food itself also has the gene to kill insects, but pests can rely on elimination and evolution to produce higher resistance to this characteristic, resulting in the possibility that pesticides cannot be killed.

Reduction of non-GMO crops. Genetically modified crops are cheap, good seeds, and large yields, so many farmers are willing to plant genetically modified crops, such as the traditional non-GMO soybean production area in Northeast China, where local soybeans are reduced year by year and replaced by genetically modified soybeans, which is likely to lead to the suspension and extinction of non-GMO crop seeds.

Benefits of genetically modified foods:

1. It can increase the yield per unit area of crops; Production costs can be reduced.

Second, through genetically modified technology.

It can enhance the ability of crops to resist pests and viruses.

3. Improve the storability of agricultural products, extend the shelf life, and meet the increasing needs of the people's living standards.

Fourth, it can greatly shorten the time for crop development; It can get rid of the influence of seasons and climate, and the four seasons are low-cost**; Break down species boundaries and continue to breed new species to produce food that is good for human health.

Disadvantages of genetically modified foods:

1. Genetically modified products because of genetic recombination.

The reason may cause some unknown changes in the organism, and even the nutritional content has also changed.

2. Genetically modified crops may eventually grow into weeds and are difficult to remove.

3. Genetically modified organisms may re-birth some new diseases or viruses and so on.

4. Genetically modified organisms may further damage biodiversity.

Eventually, many creatures become much the same.

The threat of genetically modified foods to the ecological environment:

Genetically modified organisms disrupt the ecological balance.

Impacts on biodiversity. Moreover, if the evolution rate is too fast, new viruses or harmful species may be produced, and genetic contamination may be generated to accelerate the evolution of organisms in some aspects, but for the whole ecology, it will destroy the evolutionary balance of organisms and lead to ecosystems.

Deformity or pathological development.

Genetically modified crops have certain advantages over non-genetically modified crops, lack of natural enemies and strong adaptability to the external environment, a large number of individuals appear in a short period of time, and a large number of genetically modified organisms are likely to hybridize with wild species after entering nature.

This kind of horizontal drift of genes between species breaks the original ecological balance, which may cause "genetic pollution", thereby affecting the conservation and sustainable use of biodiversity, and causing harm to the environment and ecosystems that is more difficult to eliminate than any other factors that cause pollution to the environment.
