Can we regrow damaged seagrass meadows?
Seagrass meadows, which offer coastal protection, biodiversity support, and carbon storage, are facing significant degradation. Approximately 30% of these vital ecosystems have been lost since the late 19th century, raising questions about their potential for regeneration.
Seagrass protects coasts, shelters thousands of species and stores CO2. But some 30% of this valuable ecosystem has disappeared since the late 19th century. Can we bring it back?
Background
Seagrass is a marine flowering plant that forms underwater meadows in coastal areas. These ecosystems play a crucial role in maintaining marine health by stabilizing coastlines, providing habitats for numerous marine species, and sequestering carbon dioxide from the atmosphere. Their widespread decline highlights a significant environmental concern.
Why it matters
The loss of seagrass meadows diminishes coastal resilience, leading to increased erosion and vulnerability to storms. Their disappearance also threatens marine biodiversity and reduces the ocean's capacity to absorb atmospheric carbon.
Possible impact
The continued loss of seagrass could lead to greater coastal damage and increased greenhouse gas concentrations. Successful regeneration efforts could bolster natural defenses against climate change and support marine life.
