What are the advantages of transgenic crops?

Genetically modified food has many advantages: it can increase crop yield; The production cost can be reduced; Can enhance the ability of crops to resist pests and viruses; Improve the storage resistance of agricultural products; Shorten crop development time; Remove the supply of four seasons; Breaking species boundaries, constantly cultivating new species and producing food beneficial to human health. Genetically modified food also has disadvantages: the so-called increase in production is achieved without environmental impact, and if it encounters natural disasters such as rain and snow, it may reduce production even more. Many studies have shown that genetically modified foods are harmful to the immune function of mammals. Moreover, after the experimental hamster ate genetically modified food, the third generation became extinct.
