Biodiversity underpins human survival by supporting essential ecosystem services. Diverse soil organisms contribute to soil formation and nutrient cycling. Plant roots, a component of biodiversity, help prevent soil erosion by binding the soil. Decomposers, also part of biodiversity, play a crucial role in the recycling of waste. Furthermore, a vast array of insects, birds, and other animals, key elements of biodiversity, are essential for the pollination of crops, which is vital for food security.
