This interactive activity examines the three primary ecosystems of Pacific high islands and atolls. These ecosystems—terrestrial, coastal, and reef—provide many services to island communities. However, they also face threats from both human activities and climate change. The interactive activity details the services and the threats. It also provides real-life examples of Pacific Island communities that are already experiencing changes and taking action. These actions, or adaptations, are designed to strengthen their ecosystems and the overall resilience of their island.
