The key answer of exercise 7

The topic of GM foods is controversial because people have strong opinions on it. However, which argument is the strongest: for or against?

GM food technology definitely has advantages. Firstly, it can help fight world hunger. It can produce crops that can survive droughts and pests and so prevent famine. Secondly, it is environmentally friendly. It does not require the use of chemical pesticides so it reduces pollution.

However, there are also some disadvantages. Firstly, GM food production is an unnatural way to grow crops. Modifying the DNA of a plant is interfering with nature. In addition, GM foods could cause health problems. They have not been around for long enough to see if there are any long term health effects of eating them.

All in all, although there are disadvantages to GM foods, I think they are a good idea. I think they can solve the problem of world hunger, help the environment and reduce the use of chemicals and pesticides on crops so they are healthier.
