The movement of people, the import and export of goods, and mass communication have all played major roles in shaping our world. People everywhere interact. They travel from place to place and they communicate. We live in a global village and global economy.People interact with each other through movement. Humans occupy places unevenly on Earth because of the environment but also because we are social beings. We interact with each other through travel, trade, information flows (E-Mail) and political events.Not only do humans move but also ideas move; fashions move; fads move. What is an example of an idea that moves? Fashion? Fad? How do we depend on people in other places? How would our lives change if our movement options changed? What would happen if we traveled by camel or horse? How do we move from place to place? How do we actually get food?
