Biodiversity and Its Importance

This session introduces biodiversity, its definition, and significance. It covers the components of biodiversity, including genetic, species, and ecosystem diversity. The importance of biodiversity is highlighted, emphasizing its role in ecosystem productivity, adaptation, and balance. The session also explores the ecological, economic, and scientific roles of biodiversity. It concludes with a summary and a preview of topics for the next session, including biodiversity levels and hotspots.
