Question
Read the article on page 127 about supermarket shopping and the environment. Find out four things you shouldn’t buy. Explain why.
Answer
- New Zealand kiwi fruits – flown a long distance, creating carbon dioxide / packaged in polystyrene, which is hard to recycle
- Bottles of water / cans of cola – have to mine tonnes of rock to get the aluminium for cans / transport costs
- Small bottles / small boxes of cereal – use more material than large ones
- Meat (beef and lamb) – animals produce natural gas that causes global warming / inefficient way to get food energy
