14. Biodiversity and Conservation

Biodiversity encompasses the variety of life on Earth, which is fundamentally vital for human existence. It plays significant ecological, economic, and scientific roles, with three primary levels: genetic, species, and ecosystem diversity. However, human activities have led to a rapid decline in biodiversity, necessitating concerted conservation efforts.
