Sustainable development is global progress balancing economic growth, social inclusion, and environmental protection, meeting today's needs without harming future generations, best exemplified by the UN's 17 Sustainable Development Goals (SDGs) (ending poverty, protecting the planet, ensuring peace/prosperity by 2030). It requires shifting towards renewable energy, responsible consumption (tackling food waste), inclusive policies, and innovation, though challenges remain in balancing growth with environmental limits, as seen in India's efforts and ongoing global debates.
