IV. Speaking Out
MODEL 1   Why are people protesting against
             genetically modified foods?
Susan: With so many people suffering from malnutrition around the world, why are people protesting against genetically modified foods?
Chris: Some people are protesting about genetically modified foods, but even more people are protesting the fact that processed foods containing these ingredients aren’t labeled.
Susan: But why should they be labeled?
Chris: Not everyone is sure that genetically modified foods are safe. They want to be certain that biotech foods have the sme composition as organic foods.
Susan: But there are more urgent problems in this world. Many people are dying of starvation.
Chris: But those who aren’t starving may want genetically modified foods to be labeled so they know what foods they should andd shouldn’t eat.
Susan: You know, I heard of a genetically modified fish that grew to be ten times its normal size.
Chris: That sure sounds abnormal.
Susan: Yeah, it does sound a bit strange , but that fish could feed ten times as many people.
Chris: You’re right; genetically modified food might help solve world hunger. But I think we have a right to know what we are eating.
