Advantages
- Crops are genetically engineered to produce their own pesticides so they can kill the insects that attacks them. They can also be resistant to herbicides used to control weeds.
- Producing insulin using bacteria allows us to make insulin on a large scale.
- We use genetic engineering to improve the growth rates of plants and animals. This can improve the food value of crops as genetically modified plants have bigger yields than ordinary plants. These crops can be grown in dry or cold climates so they can solve world hunger.
- Genetic engineering can cure genetic diseases by putting healthy genes into the affected cells so they would work properly.
- No one knows the long-term effects.
- Insects may become resistant to pesticides if they keep eating pesticide-forming plants.
- GM foods may have a bad effect on human health. These crops are infertile so the farmers have to buy new seeds each year.
