📖 Reading Passage

The concept of 'environmental sustainability' has evolved significantly over the past decades, moving from a peripheral concern to a central pillar of global policy. Initially, sustainability was often narrowly interpreted as the efficient management of natural resources to prevent depletion. However, contemporary discourse recognizes that environmental health is inextricably linked with social equity and economic viability. This holistic perspective, often termed the 'triple bottom line', argues that long-term progress is unattainable if ecological degradation disproportionately affects vulnerable communities or if economic growth undermines the very ecosystems it depends on. Consequently, modern sustainability frameworks emphasize integrated approaches, requiring policymakers to consider the cascading impacts of their decisions across multiple domains. Critics, though, contend that such broad definitions can become too vague to guide concrete action, potentially diluting the urgency of specific environmental crises. Nevertheless, the shift reflects a growing acknowledgment that environmental problems are not isolated technical issues but are deeply embedded in complex socio-economic systems.
