👉 Natural engineering refers to the processes and structures that occur spontaneously in nature without human intervention, showcasing the inherent efficiency and adaptability of ecological systems. Examples include the formation of river deltas through sediment deposition, the self-cooling properties of termite mounds that maintain stable internal temperatures, and the intricate network of mycorrhizal fungi that enhances nutrient absorption in plants. These phenomena demonstrate how nature has evolved sophisticated solutions to environmental challenges, providing valuable insights and inspiration for sustainable engineering practices.
