Crop diversity is the variety of different kinds of crops that are grown. Just like people are different, different crops have their own unique qualities. The purpose of having diverse crops is to make sure there is enough food to go around and that the food is healthy. Having different crops also helps protect against diseases that could wipe out an entire crop if it was all the same type. Diversity also means that different types of food can be grown in different areas, which allows people to have more options for healthy, tasty food.
