They have it backwards---climate change kills seagrass faster than we can plant more of it.
OBIS ’23 [Ocean Biodiversity Information System; November 28; “Preserving Seagrass in a Changing Climate,” https://obis.org/2023/11/28/seagrass-model/]
Except for Antarctica, about 70 seagrass species can be found in coastal and marine environments around the world. Often forgotten, seagrasses provide critical ecosystem services which rival those of coral reefs and mangroves. They offer critical shelter, nursery, and foraging grounds for an incredibly diverse community of ocean life. They also stabilize sediments, store carbon, absorb excess nutrients and produce life giving oxygen. However, seagrass meadows are disappearing at an alarming rate of 0.9% to 7% per year because of human activity such as pollution, dredging, anchoring and coastal development. With climate change impacts expected to exacerbate the situation, it is becoming urgent to understand how seagrass communities will be affected.
