Now Your Turn
Task 1
SAMPLE DIALOG
Jane: Some countries are suffering from crop failure and famine, but why do they refuse genetically modified crops and foods?
Bob: And many Europeans insist that processed foods containing GM ingredients be
labeled.
Jane: Why should they be labeled?
Bob: Not everyone is sure that genetically modified foods are safe. They want to certain that biotech foods have the same composition as traditional foods.
Jane: But there are more urgent problems in this world. Many people are dying of famine.
Bob: But those who aren’t hungry may want all genetically modified products to be labeled so they know exactly what they’re eating.
Jane: You know, I’ve heard of a GM fish that was ten times larger than a normal fish.
Bob: That really sounds abnormal.
Jane: Some famine-stricken people are afraid GM crops will overpower and eliminate their native crops.
Bob: Sounds alarming.
Jane: Yeah, but GM foods can feed many people.
Bob: You’re right; they could solve the problem of starvation in the world. But I think we have a right to know what we are eating. GM food should be labeled.
