The term for the study of biological diversity across the planet is biodiversity. This field examines the variety of life forms, including species, genetic, and ecosystem diversity, and their distributions across different environments. Biodiversity is essential for ecosystem resilience, resource availability, and overall environmental health. Researchers study biodiversity to understand evolutionary processes, track changes due to climate change or habitat destruction, and develop conservation strategies to protect endangered species. Ultimately, biodiversity underpins the strength and stability of ecosystems.
