Question
Work in groups. Discuss the questions.
Answer
- The first family uses too much packaged food, in particular bottles and cans of drinks, jars, boxes and tins. They eat no fresh local food, but they also have no meat or dairy products in their shopping, and both of these are bad for the environment.
- The second family eats much more fresh, unpackaged food (fresh fruit and vegetables) which looks as if it is locally produced, but they buy tins, glass jars and bottles, and plastic trays of meat. Meat is also bad for the environment.
- The third family is the most environmentally friendly, their food looks mainly locally produced, and they use very little packaging. The only packaging is large sacks, which is efficient as there is less packaging relative to the volume of food. Cloth is more environmentally friendly than plastic.
