In many ways, the world is one country. Our common needs and experiences bind us together as one family. But different groups of people eat different foods, wear different clothes, have different customs. This beautiful diversity is part of what makes life on Earth so interesting. It's why people love to travel - to learn about other cultures, or ways of living.
Diversity is an important key to the future.
Anthropologists, or scientists who study cultures, say there is much to learn from all the world's peoples. Others are newer. Some are fighting for survival and may soon disappear. In hundreds of cultures around the world, people struggle to survive and build happy lives. Each individual has a contribution to make to our beautiful, diverse human family.
