People everywhere must have certain things in order to live. With out water, we could live for less than a week. With out food, they could live less than a month. They must have clothes so that their bodies are protected. Shelter or places where people live, covers and protects them from weather. Food, water, clothes and shelter are basic needs. Basic need are the things all to stay alive.
People have other needs that are important to them. But they do not need them to stay alive. One is a need to feel safe. Another is a need to learn new things. Another is a need to be loved and another is a need to have fun.
Most people cannot meet their basic needs by themselves. This is an important reason why they live together in communities. There, by working together, they help each other to meet these needs.
Communities must find a water supply. The climate of a community plats a part in the type of clothing and shelter people will need. Climate is the kind of weather a place has most of the time. In a community with a hot climate, people need clothes and shelter to keep them cool. People in a community with a cold climate need clothes and shelter to keep them warm.
