Simply put, culture is the stuff people make and the learned conventions that people live by. People create art, sports, and politics as just a few examples. Culture also includes the acceptable ways to react and interact with different areas of life. For example, the proper conduct when first meeting someone.
A culture can be so ingrained in a person that cultural norms are mistaken for a fact of life. For example, in North Americans see avocado one way – as an ingredient served only for savory dishes. But did you know in Asia, avocado is used used primarily for desserts! Avocado smoothie, anyone?
And contrary to popular belief, DNA does not equal culture. Culture is learned. Culture is fluid. Culture can be molded and changed. It’s why culture has changed with the ushering in of technological advances and social movements with the most recent being the internet and information age.
