An estimated 730 million people—about 9% of the global population—live on islands. These places shelter delicate ecosystems and rare species that have survived for millennia. For instance, Iceland’s Grimsey Island is home to millions of seabirds.

Islands also provide crucial insights into evolution. Madagascar, separated from other landmasses millions of years ago, forced its wildlife to adapt in unusual ways. Unique creatures like the leaf-tailed gecko evolved to camouflage perfectly against predators. Many species here exist nowhere else on Earth.

Yet scientists warn that islands such as the Maldives, Fiji, Micronesia, and Tuvalu face the risk of being submerged by the century’s end. In fact, some of the Solomon Islands have already disappeared, displacing their communities. Even its famous non-stinging jellyfish population has nearly vanished.

Climate change continues to accelerate this crisis. Rising sea levels and warmer oceans cause more frequent floods, coral bleaching, and marine extinctions. Corals, vital to marine ecosystems, are especially vulnerable to rising temperatures, threatening countless species that rely on them.

International efforts are underway to safeguard islands, but everyday actions also matter. Choosing renewable energy, reducing waste, supporting sustainable tourism, and buying eco-friendly products can all help slow the impacts of climate change and protect these fragile lands.
