Peat bogs are areas of land, which are very acidic and waterlogged. Therefore
the plants that live in that environment do not fully decay so they trap the
carbon within the peat bog.
Therefore the plant does not release any carbon into the atmosphere and it
is locked within the peat instead.
However due to the population increasing, there is an increased demand
for food, therefore more land is needed for agriculture. When farmers
come across peat bogs, the eat bogs are drained and the plants begin
to decay. This adds to the compost fro farmers but now the carbon is
released into the atmosphere, which adds to the greenhouse effect.
