The term "natural materials" refers to substances that are derived from natural sources and do not contain any synthetic or artificial components. These materials can be found in various forms, such as wood, cotton, wool, leather, and many others. They have been used by humans for thousands of years for a wide range of purposes, including clothing, shelter, transportation, and artistic expression. Natural materials are often valued for their unique properties, such as strength, flexibility, insulation, or beauty. In recent times, there has been a growing interest in using natural materials due to concerns about the environmental impacts of synthetic materials, as well as a desire to return to more sustainable and traditional ways of living.
