Complete the text with who, why, where and which. people who want to protect the environment are usually careful about the origin of their food. food comes from local producers is ok, but the countries farmers grow exotic fruits are often thousands of kilometres from our shops. a good example is kiwi fruit comes by plane from new zealand. the boxes of fruit arrive at our airports lorries are waiting to transport them to supermarkets. the supermarkets sell this product are often out of town, si people buy kiwi fruit must drive there. all in all, that's a lot of boxees and fuel - a lot of waste. that's imported food is bad for the environment.
