Degradation processes refer to the various ways materials and ecosystems deteriorate over time due to environmental factors. These processes can be physical, chemical, or biological, leading to a loss of functionality or structural integrity. For instance, corrosion in metals occurs when they react with moisture and oxygen, resulting in rust and weakening of the material. In ecosystems, degradation can manifest as habitat loss or soil erosion, often driven by human activities like deforestation and pollution. Understanding these processes is crucial for developing strategies to mitigate their effects and promote sustainability in both materials and natural environments.
