Human Systems # 4 Human systems is one of the six essential elements of geography. Geographers study how people shape the earth’s surface. They examine how people move from place to place, how they settle the earth, and how they form societies. Some people travelfrom place to place. Others talk to people around the world by telephone, mail, and e-mail. The Internet, radio, television, and books spread different ideas and ways of life.
Goods and services are also exchanged around the world. Some of the clothes we wear comes from other countries. In turn, we send other countries things they need that we produce. In short, we need other countries, and they need us. No country in the world today can survive strictly on its own. The word we use to describe this relationship is interdependence. This is also known as globalization!
