For example, Cui Yongyuan and his spin doctor Chen boasted that they found "unknown pathogens" in genetically modified soybeans, which could have won the Nobel Prize in Physiology and Medicine, but everyone knew that they knew nothing about biological knowledge, and anyone with a little common sense knew that they were making rumors. In addition, Chen played a disgraceful role in the "water to oil" fraud case. If you don't believe me, just look at the photos below.
Russian Campbell hamster experiment, French transgenic corn tumor experiment, and so on, are as inexplicable as Cui Yongyuan's "discovery"!
If you really want to win this debate, you'd better make a fuss about the possible environmental impact of genetically modified crops. Of course, you can't find valuable examples, but you can "analogy".
Your opponent in the debate can come up with a lot of comments on genetically modified foods from the most authoritative international organizations, which cannot be refuted in your debate.
If your opponent is not too bad, you have no chance of winning!
