Biodegradable materials are substances that can break down naturally through the action of living organisms, such as bacteria and fungi. These materials decompose into natural elements, returning to the environment without causing harm. Common examples include food waste, paper, and certain plastics designed to degrade over time. The process of biodegradation typically occurs in composting or natural environments, where microorganisms consume the material. This helps reduce waste in landfills and minimizes pollution. Using biodegradable materials can contribute to a more sustainable lifestyle by decreasing the accumulation of non-decomposable waste in our ecosystems.
