backpedaling.
i come up with about 210 for 2008, which isn't very close to equaling the top two.
"Termites. Global emissions of methane due to termites are estimated to be between 2 and 22 Tg per year, making them the second largest natural source of methane emissions. Methane is produced in termites as part of their normal digestive process, and the amount generated varies among different species. Ultimately, emissions from termites depend largely on the population of these insects, which can also vary significantly among different regions of the world. "
