Peat is a dark, organic material that forms in waterlogged areas, known as peatlands or bogs. It develops over thousands of years from the accumulation of partially decayed plant matter, primarily mosses like sphagnum. Peat is important for the environment as it stores carbon, helping to regulate the Earth's climate. People often use peat as a natural resource for gardening and fuel. In gardening, it improves soil structure and retains moisture, making it beneficial for plant growth. Additionally, in some regions, peat is burned as a traditional fuel source, providing heat and energy, although this practice raises environmental concerns due to carbon emissions.
