At the beginning of human history, people could only eat food they found. But then people learned to find more ways to get food. About 10, 000 years ago people started to farm the land. After that, people developed farming skills. 

People eat different food in different areas. In China rice is the main food for people in the south while the people in the north eat noodles. People who live in European countries near the sea eat lots of fish. But in Central Europe, people are away from the sea. So they don't eat so much fish. They eat more special meat instead.

People eat food with different tools in different areas. In China, people always like using chopsticks while in North American, Australia and Europe, people always like using knives and forks, to our surprise, in India and the Middle East, people always pick up food with their own fingers. 

Now people can eat different food from different areas. As we can see it is possible to convey food easily from one part of the world to another. We can almost eat whatever we like at any place of the world. For example people in Britain can eat bananas from Africa and rice from India. Food is becoming a very big business now.
