Peatland
Wetland ecosystem dominated by peat (partially decomposed plant material) storing vast carbon quantities.
Real World
Indonesia's tropical peatlands store an estimated 57 billion tonnes of carbon, but drainage for palm oil plantations caused catastrophic peat fires in 2015 that released more CO₂ daily than the entire US economy.
Exam Focus
Emphasise that peatlands are both carbon stores (existing stock) and carbon sinks (ongoing sequestration) — use both terms precisely for full marks.
