What is the relationship between biodiversity and ecosystem health?

Higher biodiversity usually indicates a healthier ecosystem because a wide variety of species contributes to the resilience and functioning of ecological systems. Diverse ecosystems can better withstand environmental stressors, such as climate change or disease, and are more capable of providing essential services, such as clean air, water, and fertile soil. A high level of biodiversity means that there are various organisms that can perform different roles, such as pollination, decomposition, and nutrient cycling. This complexity allows ecosystems to adapt to changes and recover from disturbances more efficiently. In contrast, ecosystems with low biodiversity may be more vulnerable to disruptions, leading to a decline in ecosystem health.
