4PLANET IMPACT / ISSUE
Coastal ecosystem loss
Mangroves, seagrasses, salt marshes, reefs and other coastal ecosystems face multiple pressures from development, pollution and climate change.
Why it matters
Coastal ecosystems support biodiversity and people, but risks and restoration feasibility are strongly place-specific.
What the sources establish
IPCC AR6 finds coastal ecosystems are increasingly exposed to climate and non-climate pressures, with risks rising as warming increases.
