A marine scientist for GEOMAR snorkels back to the boat after collecting flowering seagrass to harvest the seeds, in Laboe, Germany, July 17, 2023. Europe alone lost one third of its seagrass areas between the 1860s and 2016, one 2019 study found, releasing carbon into the atmosphere and speeding up global warming. While there are other initiatives to restore the plants worldwide, the SeaStore Seagrass Restoration Project in Kiel, run by the GEOMAR Helmholtz Centre for Ocean Research is one of the first that aims to enable citizens to do so autonomously.
