Alternative natural materials

Alternative natural materials are materials from nature that can be used instead of the materials that are produced by humans. Examples of natural materials are wood, stones, sand, clay and leaves. Natural materials can be used for building houses, making tools, creating art, and keeping us warm. They have been used by people for thousands of years, and are still being used today. Natural materials can be strong, light, and durable, and they don't always harm the environment like some materials created by humans.
