Unit 6 Earth first Developing ideas 1 How much do you know about “green living”? Are your choices really green? What is the function of the red parts? What is the structure of the passage? Read and find whether you made green choices. Some “green truths” have been shown to be only half true, or even completely false. Are they half true, or completely wrong? Paper bags are not good for the environment. Turning off a device won’t stop it from using power. Eating local food isn’t always better for the environment. It’s not always better to take a shower than a bath. P92 Complete the cause-effect flow chart. Devices turned off go into stand-by mode and still use power. Local produce sometimes might use more energy and produce more greenhouse gases. If you spend more than 8 minutes in a shower, you’ll use as much wate as in a bath. 7 Think and share 1. Which of the “green truths” surprises you most? 2. Are you aware of any other “green truths” that are not true? Do you know the word “greenwashing”? What does the picture indicate? Greenwashing is the practice of making brands appear more sustainable than they really are. It may involve simply changing the packaging of existing product while continuing to use unsustainable ingredients or practices. Can you think of any examples? McDonald’s paper straws Coca-Cola Life (6.6% sugar means healthy/sustainability?) H&M (Conscious?) What does fast fashion do to the environment? What should we do? Buy less. Choose well. Make it last. $
