Freshwater wetlands are a major source of the greenhouse gas methane but at the same time can function as carbon sink. Their response to global warming and environmental pollution is one of the largest unknowns in the upcoming decades to centuries. In this review, we highlight the role of ,sulfate,-,reducing, microorganisms (SRM) in the intertwined element cycles of wetlands.
