This increase has particularly taken place in developing countries, of which Indonesia, China, Malaysia, and Papua New Guinea are the fastest-growing top emitters. In addition to being soft in texture and therefore suitable for demersal (bottom-dwelling) species such as Corydoras catfish, peat is reported to have a number of other beneficial functions in freshwater aquaria.

Sicklebrook publishing, Sheffield, U.K. Keddy, P.A. [3] Globally, it even stores up to 550 gigatonnes of carbon, representing 42% of all soil carbon and exceeds the carbon stored in all other vegetation types, including the world's forests. Cambridge University Press, UK. [48], The extraction of peat from the Somerset Levels began during the Roman times and has been carried out since the Levels were first drained.
