Food Around the World
For 99% of human history, people took food from the world around them. They ate all that they could find and then moved on. Then about 10,000 years ago, or for 1% of human history, people learned to farm the land and control their environment.
What do we eat? The kind of food we eat depends on which part of the world we live in, or which part of our country we live in. For example, in the South of China they eat rice, but in the North they eat noodles. In Scandinavia they eat a lot of herrings, and the Portuguese love sardines. But in central Europe, away from the sea, people don’t eat so much fish, they eat more meat and sausages. In Australia, Germany and Poland there are hundreds of different kinds of sausages.
How do we eat? In North America, Australia and Europe there are two or more courses to every meal and people eat with knives and forks. In China there is only one course, all the food is together on the table, and they eat with chopsticks. In parts of India and the Middle East people use their fingers and bread to pick up the food.
Where does our food come from? Nowadays it is possible to transport food easily from one part of the world to the other. We can eat what we like, when we like, at any time of the year. Bananas come from the Caribbean or Africa; rice comes from India or the USA; strawberries come from Chili or Spain. Food is very big business. But people in poor countries are still hungry, and people in rich countries eat too much.
