Biodiversity is crucial for maintaining healthy ecosystems and supporting life on Earth. It ensures **ecosystem stability**, with diverse species contributing to processes like pollination, water purification, and nutrient cycling. High biodiversity enhances **resilience**, helping ecosystems recover from disturbances like climate change or natural disasters. It provides humans with essential resources, including food, medicine, and raw materials, while promoting **genetic diversity**, which is vital for species adaptation and survival. Biodiversity also holds cultural, recreational, and aesthetic value. Preserving biodiversity is critical to maintaining ecosystem services and ensuring the well-being of all living organisms, including humans.
