Oh, please.
Yet another enviro-scare. Carbon monoxide (CO), “ozone layer” depletion, carbon dioxide (CO2), and now methane, besides all the dozens I haven’t mentioned.

Don’t forget radon gas, toxic mold, monster in the closet, monster under the bed and drunken stepdad!
Methane is a much better “greenhouse” gas than CO2. There are HUGE pockets of methane hydrates in the ocean floor - somehow they are trapped below the sediments, and folks are trying to come up with ways to make it practical to mine/drill them as a source of energy.
In the geologic past, sometimes these pockets are disturbed and the methane is released in a catastrophic manner that DOES cause problems. “Leakage” from some peat bogs is not that big of a deal.
