I think the main advantage of these three points, first of all solve the problem of food shortages, followed by the type of food can be increased to increase the nutrition of food, thereby increasing the quality of the food, and finally reducing the use of pesticides, reduce environmental pollution to a certain extent. Drawback is that transgenic technology causes biological contamination and will affect agriculture and the environment.
