Answer
- Family 1 probably spends the most as they eat a lot of packaged products, which are more expensive than fresh foods. However, they have not got any meat, which is more expensive. Their diet looks less healthy, they eat a lot of processed foods, which contain a lot of sugar, salt and other additives. They probably cause most damage to the environment because they consume so much packaging.
- Family 2 probably spend quite a lot. Their diet includes meat, which is expensive, but they eat a lot of vegetables, which are usually cheap. They don't eat a lot of packaged foods and their diet looks quite healthy. They use less packaging than 1, and their vegetables look locally grown, so they will need less transport.
- Family 3 uses very little packaging, and no plastics, which is better for the environment than 1 or 2, and also cheaper. The foods look locally grown. They eat a lot of fresh vegetables, which is very healthy.
