Although the basic genetically modified food is to increase yield, increase insect resistance and so on; But because, after all, it is thought that the DNA of crops has been modified, as to what impact it will have in the future and whether it will have an impact on the human body, everything is still unknown; Countries and institutions around the world have different attitudes: basically, Europe is against waves; North America, on the other hand, agrees, or doesn't care/ignores more.
For example, Monsanto, the most famous genetically modified seed company in the United States, has basically monopolized the seed market in the United States, and farmers have no way to save their own seeds, because in the United States, the seeds of genetically modified crops have patent rights and cannot be saved by themselves, and they must be purchased from seed companies every quarter; Natural crops can keep their own seeds because they have no patents.
80% of rapeseed oil in Canada comes from genetically modified crops.
North America is relatively open to genetically modified crops, in fact, because for large companies, the benefits are greater.
Europe is relatively conservative, farmers and various protection agencies have frequent opposition activities, and the opinions of the government and the people are quite different. There seems to be no formal conclusion yet.
I don't remember Japan very much. It seems to be relatively open in the past, and there have been many voices of opposition in recent years.
