What is the material that does not rot away naturally?

Materials that do not rot away naturally typically include plastics, metals, and glass. Unlike organic materials, which decompose over time due to biological processes, these substances can persist in the environment for hundreds to thousands of years. While they may not decompose, they can still break down into smaller particles through processes like photodegradation or mechanical wear. However, their resistance to natural decay raises concerns about pollution and environmental impact.
