Biodiversity refers to the variety of life forms within a given ecosystem, habitat, or on Earth as a whole. It encompasses the diversity of species, genetic variations within those species, and the ecological complexes they form. High biodiversity is essential for ecosystem stability, resilience, and productivity. It also provides humans with various resources, including food, medicine, and emotional benefits derived from nature. Biodiversity is threatened by factors such as habitat destruction, climate change, pollution, and invasive species, making its conservation crucial for maintaining the balance of ecosystems and ensuring the survival of numerous species, including humans.
