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. Recent research by Thompson et al. (2022) suggests that resilience is not a static property but varies with the intensity and frequency of stressors. For instance, coral reefs exhibit remarkable recovery after mild bleaching events, yet prolonged thermal stress can trigger a regime shift to algal-dominated states, from which return is unlikely. This underscores the importance of temporal dynamics in assessing ecosystem health. Critics argue, however, that focusing solely on resilience may overlook the intrinsic value of pristine habitats, which are irreplaceable regardless of their adaptive potential. Thus, while resilience offers a pragmatic framework for conservation, it should complement, not replace, biodiversity preservation efforts.
