📖 Reading Passage

The concept of 'ecological resilience' has gained significant traction in environmental science, moving beyond the traditional focus on stability. While stability emphasizes a system's ability to return to its original state after a disturbance, resilience refers to the capacity of an ecosystem to absorb disturbance and reorganize while undergoing change so as to retain essentially the same function, structure, identity, and feedbacks. This distinction is crucial because many ecosystems, particularly those affected by climate change, may not return to their pre-disturbance state. Instead, they may shift to an alternative stable state that still provides essential services. Researchers argue that management strategies should therefore prioritize enhancing resilience, for instance by maintaining biodiversity and reducing other stressors, rather than merely attempting to resist change. This proactive approach acknowledges the inevitability of some alterations and focuses on sustaining the system's core functions in the face of ongoing environmental flux.
