Through the Internet or by plane, you can visit almost anywhere in the world. This increase in social interaction makes the study of humanity vital for etiquette and understanding of other cultures and peoples. With such a globalized economy it's important to understand cultural diversity, particularly how it relates to everyday life. Many of today's careers involve travel and meeting with people around the world. An appreciation of diversity is helpful when dealing with other cultures.
Anthropology allows us to look throughout history at past cultures and civilizations. In this way, we can understand why people formed societies, prayed to certain religious deities and ate certain foods. Each of these was a building block to modern culture.
Through anthropology we are able to study and reflect on humankind's heritage. Linguistics opens the door to ancient languages that are widely unused today. Biological anthropology teaches us about the humanoid man and how we evolved to our present state. It is impossible to understand our world today without the perspective of how we got here.
