Angela Stevenson, 39, a marine scientist for GEOMAR, demonstrates the seagrass planting technique to members of maritime conservation group Sea Shepherd during a two-day citizen diver course that aims to re-green the Baltic Sea in Maasholm, Northern Germany, July 2, 2023. The citizen diver course is part of the SeaStore Seagrass Restoration Project at GEOMAR and is one of the first initiatives to teach and enable citizens to restore seagrass autonomously. Stevenson guided the citizen divers to plant 2,500 shoots during the weekend. "Our aim is to scale it up after this pilot period," said Stevenson. "The ultimate goal is to re-green the Baltic Sea."
