Biodiversity plays a critical role in global health by maintaining ecosystem stability and resilience. Diverse ecosystems support a variety of species that contribute to food security, medicines, and essential ecological processes, such as pollination and nutrient cycling. Healthy ecosystems can also mitigate the impacts of climate change by sequestering carbon and controlling pollution. The loss of biodiversity can lead to the emergence of diseases, impacting both human and animal health. Thus, preserving biodiversity is not only vital for ecological balance but also for ensuring a sustainable future for global health.
