Biodiversity refers to the variety of life forms on Earth, including the different species of plants, animals, fungi, and microorganisms, their genetic diversity, and the ecosystems in which they live. It encompasses the richness and variety of life at all levels, from genes to species to ecosystems, and plays a crucial role in maintaining the balance and health of our planet's ecosystems. Biodiversity is essential for ecosystem stability, resilience, and productivity, and provides numerous benefits to humans, such as food, medicine, clean water, and a stable climate.
