📖 Reading Passage

The concept of 'environmental resilience' has gained traction in ecological studies, referring to an ecosystem's capacity to absorb disturbances while maintaining its fundamental structure and functions. Unlike mere resistance, which implies static defense against change, resilience emphasizes dynamic adaptation. A resilient forest, for instance, may suffer partial damage from a wildfire but can regenerate through natural succession, preserving biodiversity over time. However, researchers caution that resilience is not limitless; anthropogenic pressures, such as habitat fragmentation and climate change, can erode this capacity, pushing ecosystems toward irreversible thresholds. Recent studies suggest that enhancing connectivity between habitats and reducing chronic stressors are more effective strategies for bolstering resilience than focusing solely on preventing acute events. This shift in perspective underscores the need for proactive management that anticipates future perturbations rather than merely reacting to past ones.
