📖 Reading Passage

The concept of 'environmental sustainability' has evolved significantly over the past decades, moving from a purely ecological perspective to one that integrates economic and social dimensions. Initially, sustainability was primarily concerned with conserving natural resources and protecting ecosystems from degradation. However, as global economies expanded, it became evident that environmental goals could not be achieved without addressing poverty, inequality, and economic development. This shift is reflected in the United Nations' Sustainable Development Goals (SDGs), which explicitly link environmental health with human well-being. Critics argue that such integration dilutes the urgency of environmental action, yet proponents contend that a holistic approach is essential for long-term success. Empirical studies suggest that countries adopting integrated policies tend to show more consistent progress in reducing carbon emissions while maintaining economic growth, indicating that sustainability is not a zero-sum game but a synergistic process.
