Answer:
Resources become useful through human knowledge, technology and economic feasibility. However, uncontrolled exploitation can cause depletion and environmental degradation. India has unevenly distributed resources, so systematic planning is essential. Proper resource planning, conservation, technological development, equitable distribution and sustainable utilisation can meet present needs while protecting resources for future generations. Therefore, planned and sustainable resource use is the foundation of long-term development.
