The term "biodiversity" refers to the variety and variability of life forms within a specific ecosystem, region, or on the entire planet. It encompasses the diversity of species, genetic diversity within species, and the variety of ecosystems themselves, including the interactions between these components. Biodiversity is crucial for ecological stability, providing resilience against environmental fluctuations and contributing to ecosystem services such as pollination, nutrient cycling, and climate regulation. High levels of biodiversity tend to foster healthier ecosystems, while loss of biodiversity can lead to diminished ecosystem functionality and increased vulnerability to changes like climate change.
