Is it true or not that methane gas is a Greenhouse gas stronger than CO2?

Of course not, but it's a viable source (one of many), and it'd be a shame to let it escape into the air.

Methane pockets that leak into the atmosphere have always existed.
This process has been happening for ages though - long before we started burning dino oil.

Animals have always been pumping out methane - and they were numerous back in the days.

NASA "uses" the fact that methane is a byproduct of animal life as a "MARKER / INDICATOR...of life..." when searching for life on other worlds.

Thanks for the useful info.

I'm also favorable for biomethane as an alternative to fossil CNG. It's a relatively low-cost solution and can reduce significantly the dependence on oil from politically-unstable lands.

Humans have released many orders of magnitude more carbon back into the atmosphere than ever leaked out on it's own, and the natural balance was holding things quite steadily for 650,000 years. That is until we started burning fossil fuels.

Animal digestion gas doesn't change the balance of carbon to the air - it all came from the air relatively shortly before. Do you know what creature is the source for the greatest amount of methane? Termites. But they eat wood etc. that contains carbon that the tree/plant pulled from the air to begin with, so again, it doesn't change the long term balance of carbon dioxide in the air.
