⚡ BPSC PYQ: “Discuss the concept of sustainable development and its significance in resource management” Answer: Sustainable development meets present needs without compromising future generations’ ability to meet theirs. It balances economic growth, environmental protection, and social equity. Key principles include: using renewable resources at replacement rates, minimizing non-renewable depletion, polluter pays principle, and intergenerational equity. India’s commitment to renewable energy and environmental protection laws reflect this concept.
