Passage: Peatland rehabilitation is a core element of Ireland's biodiversity strategy. The National Parks and Wildlife Service (NPWS) aims to restore degraded peat bogs, which act as critical carbon sinks. These ecosystems, when healthy, absorb carbon from the atmosphere, but when drained or cut, they release carbon, exacerbating greenhouse gas accumulation.
Question: Based on the passage, drained peat bogs:
- AFunction as highly effective carbon sinks.
- BRelease carbon and contribute to greenhouse gas build-up.
- CHave no impact on the carbon cycle.
- DAre completely ignored in Ireland's biodiversity strategy.
