Angela Stevenson, 39, a marine scientist for GEOMAR, stands in a seagrass meadow while collecting flowering seagrass, in Laboe, Germany, July 10, 2023. Photographer Lisi Niesner spent nearly a year preparing for and shooting footage of divers picking seagrass from the Baltic Sea, as they sought to develop heat-resistant strains of the plants to withstand rising temperatures. Wearing wetsuits, masks and snorkels, a team of researchers plus Niesner set out in their small boat one early July morning off the coast of Laboe in northern Germany. The Baltic Sea is usually green and murky, but on this day was relatively clear for Laboe's "split shot." REUTERS/Lisi Niesner/ File photo
