What Role Do Deep Sea Microorganisms Play in Earth's Chemistry?

TL;DR

Deep sea microorganisms, especially those that consume methane, significantly influence Earth's chemistry and climate. They help mitigate the release of methane, a potent greenhouse gas, from ocean sediments, thereby playing a crucial role in climate regulation. Understanding their metabolic processes is vital for studying climate change and forecasting future environmental impacts.
