Focus on Issues - Genetic Modification

Product Description

We all have to eat in order to live, which is why supermarkets do such big business. A large supermarket might stock over 30,000 different items of food. But producing that food can be risky. Animals and crops take time to grow. They're vulnerable to pests and diseases, and no one can control the weather. From the earliest times when humans started to harvest crops and raise animals for food, we have realised that some breeds or varieties give better results than others. Farmers have encouraged the best sheep to have lambs, and collected seeds from the strongest crops to plant again.
