Protective coverings are materials or layers that shield objects or living beings from damage or harm. They can be found in various forms, such as clothing that protects the body from weather elements, or packaging that safeguards products during transport. These coverings serve to prevent physical injury, contamination, or exposure to harmful substances. In nature, many organisms have protective coverings as well. For example, the shell of a turtle provides defense against predators, while the bark of a tree protects it from pests and environmental factors. These coverings are essential for survival, ensuring safety and longevity in different environments.
