Complete Concept Guide (100% Curriculum Coverage)
1. Classification of Natural Resources
Resources are classified by origin (Biotic vs Abiotic), renewability (Renewable vs Non-Renewable), and development (Actual vs Potential). Fossil fuels like coal and petroleum are non-renewable because their replenishment takes millions of years.
2. Sustainable Resource Management
Sustainable development means utilizing resources carefully so that besides meeting present requirements, future generations are also catered for. The 3 Rs (Reduce, Reuse, Recycle) are the foundation of resource stewardship.
3. Human Resource: The Ultimate Asset
People are the supreme resource. Through education, healthcare, and skills, human beings transform raw rocks into silicon microchips and raging rivers into hydroelectric power.
