How human activities compromise coral health and resilience

Human activities are fundamentally altering the chemical makeup of coral reefs, according to a study led by the University of Hawai'i at Mānoa and published in Nature Communications. The research team discovered that 25 contaminants from agricultural, industrial and pharmaceutical sources accumulated in the soft tissues of corals around Maui, Hawai'i. Additionally, in areas affected by human activities, energy and nutrient availability within coral tissue decreases, making corals significantly less resilient to environmental stressors such as warmer or more acidic waters.
