The Plant that Grows Meat

B2 – Upper Intermediate

Genetically modified organisms (GMOs) are living organisms that have had their genes altered in some way. Genetic engineering can be done with plants, animals, or even bacterias.

In Iceland, researchers are growing genetically modified barley plants inside a greenhouse to create lab-grown meat. They believe that this cutting-edge approach can lower costs, enhance food production and quality, and eliminate dependence on live animals.

Let’s watch the video to learn more about the process of genetically modifying barley plants to grow meat.

Discussion Questions:

  1. What are your thoughts on this process of genetically modifying plants to create lab-grown meat?
  2. Do you think GM food is safe to eat? Explain your stand.
  3. People in the US have been eating genetically modified food for many years without ill effects. Why do you think some people in the rest of the world still have doubts?
  4. Is GM experimentation “unnatural”? Are all “unnatural” things bad? Elaborate on your stand.
