Q.Why is biodiversity so important and worthy of protection?

Step 1. The chapter frames biodiversity's importance under three headings: ecosystem services, biological resources, and social benefits of biodiversity — a structure that already signals its importance spans ecological, economic and cultural dimensions simultaneously.

Step 2. As ecosystem services, biodiversity sustains the continuity of nutrient/biogeochemical cycles, soil formation and fertility, ecosystem productivity, water trapping/filtering/regulation, and climate stability through forest cover's effect on rainfall, temperature and CO2 absorption.

Step 3. As biological resources, biodiverse regions act as reservoirs of food resources, gene pools, genetic resources, medicinal compounds and bio-prospecting opportunities — resources human society depends on directly for food security, medicine and future scientific discovery. …
