A peat-digger is a person who extracts peat, a type of organic material formed from decayed plant matter in waterlogged conditions. Peat is often harvested for use as a fuel source, soil amendment, or in gardening due to its moisture-retaining properties. The process typically involves cutting and drying the peat before it is sold or used. Peat-digging can have environmental impacts, particularly on wetland ecosystems, if not managed sustainably.
