Seagrass Ecosystems Mapped for the First Time: A Key to Fighting Climate Change

For the first time, scientists have created a global map of seagrass ecosystems. These underwater meadows cover an area roughly the size of Switzerland. The map reveals that seagrass is far more widespread than previously thought. Seagrass is a flowering plant that grows in shallow, coastal waters. It plays a critical role in fighting climate change. The plants absorb carbon dioxide from the water and store it in their roots and soil. This process, called carbon sequestration, makes seagrass one of the most efficient natural carbon sinks on the planet. The new map will help researchers and governments protect these vital habitats. It shows where seagrass is thriving and where it is under threat from human activities like fishing and coastal development. The data also supports efforts to restore damaged seagrass beds, which can boost local fisheries and improve water quality. Until now, scientists lacked a complete picture of seagrass distribution. The map is based on satellite images and field surveys from around the world. It is the most detailed record of these ecosystems ever produced.
