[QUOTE="holwellcourtfarm, post: 6365950, member: 42914"] A good discussion that doesn't ignore the nuances. This is a good summary of the methane issue: "Basically atmospheric CO2 is turned into sugar by photosynthesis. This sugar becomes plants leaves, branches, etc. Cattle eat the plants. The plants are turned into SCFA’s H2 and CH4 by bacteria and archae in the rumen. The cattle use the SCFA’s for energy and burp the (enteric) CH4. This emitted CH4 collides with hydroxyl radicals in the troposphere and is then reduced eventually back to H2O and CO2. That CO2 is then again converted to glucose via photosynthesis . The cattle eat the plants, emit the CH4, and the cyclical loop repeats itself. If the cattle don’t eat the grasses (plants), the grasses do one of three things: either die then oxidize to CO2, rot then oxidize to CH4, or burn plus emit pyrogenic forms of CH4 (as well as CO and CO2). So basically enteric CH4 is part of the respiration cycle. This form of microbial CH4 doesn’t add to the atmospheric load of CO2. It’s a lot different than thermogenic or other ancient forms of trapped methane from fossil fuels that haven’t been in the atmosphere for millions of years." [/QUOTE]
