Step 3: Warm up

A: Directions: Watch the video clip and do the exercise on P2. Or the teacher can read the passage with answers to train students‘ listening skill.

B: Discussion. (choose one of them)

1. Why would people rather pay extra money for organic food?

( Cues: chemicals; non-organically produced food; residue; pesticide; fertilizer)

Suggested Answers

Many people just don‘t trust those chemicals and don‘t want to put them into their bodies. Since virtually all non-organically produced foods contain residues of pesticides, fertilizers and other chemicals, the only way to avoid them is to buy organic foods.

2. Is organic farming less damaging to our environment? Why?

( Cues: damaging; release; ecosystem; energy; waste)

Suggested Answers

Organic farming is less damaging to our environment for the following reasons:

a. Organic farms do not consume or release synthetic pesticides into the environment—some of which

have the potential to harm soil, water and local terrestrial and aquatic wildlife although it must be noted that organic pesticides still have the potential to be as damaging to the environment as synthetic pesticides.

b. Organic farms are better than conventional farms at sustaining perse ecosystems, i. e. populations

6

of plants and insects, as well as animals.

c. When calculated per unit area, organic farms use less energy and produce less waste, e. g., waste

such as packaging materials for chemicals.
