Cow farts.... the 3rd largest source of methane release on the planet.

But everyone here realizes, (right?), that biological emissions of such
gasses do not contribute to global warming, because the carbon emitted from
a biologic, into the environment, was carbon which was recently pulled by
the biologic, from the environment. In other words, there is no net increase
in greenhouse gasses due to biological life. The problem, (if there is a
problem, and I'm not sure there is), occurs when carbon, which has been
stored deep within the earth for eons, is now pulled from the ground and
emitted into the environment, causing an increase in carbon dioxide in the
atmosphere. This would be the only cause of additional greehnouse gasses in
the atmosphere -- not biological life.
And, the only way to stop it, is to stop pulling carbon from the ground. It
doesn't help to slow down the process, or reduce greenhouse gas emissions
from cars. As long as carbon is pulled from places where it has not been a
part of the environment, into the environment, there will be a gradual
increase in CO2 in the atmosphere.
