Genetically modified products are popular in the food industry. Soya beans, potatoes, corns, tomatoes, white radishes - they have all been modified by genetic technology.
GM technology can speed up the production rate of crops and increase their yield. But does the process have no disadvantages or pose no dangers?
Despite the benefits of GM technology, we cannot know the hidden risks in products. There may be some problems that affect people's health we do not know of.
Messing around with the genetic code of living organisms, from vegetables to livestock, will affect the laws of nature. We risk upsetting the natural balances that keep us safe.
I believe we should not become reliant on GM products to feed people. Instead, we should study how to decrease population growths globally.
We should invest our resources in birth control.

From the Editor
Thank you for your letter, Vivian. The arguments for and against genetically modified foods are often passionate and quite heated. On the one hand, we have to feed seven billion people. On the other, GM foods have not been properly tested and so we don't know what long-term effects they might have. Both sides have good points. What concerns me is that we won't even know if we consume GM food because there is no law to make food producers tell us.
It is also difficult for food makers to ensure that all their products are certifiably GM-free. It is going to take us a long time to reach a happy medium between nutrition and safety. Perhaps one day we can make healthy foods taste like our favourite but unhealthy snacks.
