Please select the best answer from the choices provided

True or false

Answer 1

False.

Forests are an important carbon sink but not the only one. Other major sinks include:
- Oceans (dissolve CO2 and host phytoplankton that fix carbon) — the largest active sink.
- Soils (organic matter stored in soils and permafrost).
- Wetlands and peatlands (very high carbon density).
- Coastal "blue carbon" habitats (mangroves, seagrasses).
- Long-term geological sinks (sedimentary rocks, carbonates, and stored fossil fuels).

All of these absorb and store carbon on different timescales.
