In the past the world’s population was probably a thousand people, but now!! We are over 7.5 billion people on this planet. Our world is divided into many types of societies depending on the way of living of these people. We have horticultural societies, pastoral and many more what characterizes each one is all the activities they have. For example, pastoral societies are nomadic, they base their way of living in domesticating animals. What makes societies grow is the appearance of surplus this is extremely important, they start to specialize according to what they grow or produce. Activities start being delegated to others members and societies stratify and grow in number.
