Which practice is integral for nourishing coral ecosystems?

The practice of reducing local stressors is integral for nourishing coral ecosystems because it helps create a healthier environment where corals can thrive. Local stressors, such as pollution, sedimentation, and overfishing, negatively impact the overall health of coral reefs by degrading water quality and disrupting the delicate balance of marine ecosystems.

By addressing and mitigating these stressors, coral reefs are given a better chance to recover from disturbances, maintain biodiversity, and support the various marine life that depend on these ecosystems. Successful coral restoration often focuses on reducing human-induced pressures, as this fosters resilience in coral populations and enhances their ability to withstand environmental changes.

The other practices listed do not contribute positively to the health of coral ecosystems. Excessive fishing can deplete essential fish populations that play crucial roles in maintaining the balance of reef ecosystems. Artificial feeding can disrupt natural feeding behaviors and create dependency, potentially altering the ecosystem dynamics. Planting non-native species can introduce invasive species that compete with native flora and fauna, further destabilizing the ecosystem. Thus, focusing on the reduction of local stressors is the most effective approach to support and nourish coral ecosystems.
