Human cultures are the shared beliefs, practices, values, and customs of groups of people. They shape how individuals interact with each other and their environment. Cultures can be influenced by factors such as geography, history, and social structures, leading to diverse ways of life around the world. Examples of cultural expressions include language, art, music, and traditions. Different cultures often have unique rituals and celebrations that reflect their values and history. For instance, festivals like Diwali in India or Thanksgiving in the United States highlight the importance of community and gratitude. Understanding these differences fosters respect and appreciation among people from various backgrounds.
