Abstract
Hello, today I am going to present you the notion Spaces and Exchanges. To begin, we need to define this notion. Space is a continuous area or expanse which is free or unoccupied. Exchange is an act of giving one thing and receiving another in return. Following the Age of discovery, exchange between countries increased rapidly. Among them, we could notice an immigration flow to the new lands. In the 19th century the world has seen a big wave of immigration.
For what reasons do people emigrate and what are the consequences of those immigrations?
