13. BIODIVERSITY AND CONSERVATION
The content dives into biodiversity, highlighting its various components—genetic, species, and ecological diversity—and discussing the critical need for conservation due to the alarming rates of species loss driven by human activities. It describes the patterns of biodiversity distribution, particularly the greater species diversity in tropical regions, and emphasizes the importance of biodiversity for ecosystem functionality and survival. Effective conservation strategies are outlined, stressing both in situ and ex situ methods to protect the rich biological heritage of Earth.
