📖 Reading Passage

The concept of 'environmental refugee' has gained traction in recent decades, yet its legal definition remains contentious. Unlike traditional refugees who flee persecution, environmental migrants are displaced by gradual ecological degradation or sudden natural disasters. Scholars argue that the term 'refugee' implies a legal status under international law, which currently does not recognize environmental factors as grounds for asylum. This ambiguity creates a protection gap, leaving affected populations without formal rights or international assistance. Some propose extending the 1951 Refugee Convention, while others advocate for a separate legal framework to address climate-induced displacement. The debate underscores the tension between state sovereignty and humanitarian obligations, as nations grapple with resource constraints and border security. Ultimately, the lack of consensus hinders effective policy responses to one of the most pressing challenges of the Anthropocene.
