The concept of 'environmental resilience' has gained traction in ecological studies, referring to an ecosystem's capacity to absorb disturbances while maintaining its core functions and structures. Unlike mere resistance, which implies a static state, resilience emphasizes dynamic adaptation. For instance, coral reefs subjected to bleaching events can recover if stressors are mitigated, showcasing resilience through regeneration. However, recent research highlights that resilience is not limitless; repeated shocks can erode an ecosystem's buffer, leading to a tipping point where it shifts into an alternative, often less desirable state. This understanding challenges traditional conservation approaches that focus solely on restoring pristine conditions, urging instead for strategies that enhance adaptive capacity and manage transitions. Thus, resilience thinking reframes environmental management from a battle against change to a navigation of change, acknowledging uncertainty as a fundamental component of ecosystem dynamics.
❓ Según el pasaje, ¿cuál es una diferencia clave entre resiliencia y resistencia?
A. La resistencia implica una tolerancia pasiva, mientras que la resiliencia implica una recuperación y adaptación activas.
B. La resistencia es un concepto moderno, mientras que la resiliencia está desactualizada.
C. La resistencia se aplica únicamente a los arrecifes de coral, mientras que la resiliencia se aplica a todos los ecosistemas.
D. La resistencia se centra en prevenir todo cambio, mientras que la resiliencia fomenta un cambio sin restricciones.
✅ 正确答案
Resistance involves passive endurance, while resilience involves active recovery and adaptation.
