That can't be good! Unless it could somehow be harnessed, although that would be quite doubtful, and probably not very helpful.

Why can't this be good? Organisms have been doing this since the beginning of live. They just discus the mechanism by which it may happen.

Well methane is a greenhouse gas. Thus potential global warming increase. That's my guess of why zts16 said it can't be good.

It depends on the abundance of the plants in question: cattle, for instance, are a major contributor to global warming because they're EVERYWHERE. A lot of the problem isn't the methane itself, it's the eventual oxidation to carbon dioxide.



At the end of the day, simulating atoms doesn't beat working with the real things...

Methane is a far more potent greenhouse gas than carbon dioxide.

And yes, cattle are definitely a lot more worrisome than the plants are. I was just kinda joking about that. And their manure is too, particularly when not managed properly.

[rquote=336099&tid=31023&author=Brain&Force A lot of the problem isn't the methane itself, it's the eventual oxidation to carbon dioxide.[/rquote]

methane is ~20 times more potent as greenhouse gas than carbon dioxide which mega sucks. And if that is not scary enough [url=http://en.wikipedia.org/wiki/Arctic_methane_release]check this out[/url]. it'll just be adding fuel to the fire that is climate change...

EDIT: had to turn off bbcode to avoid this:

Just to put into perspective; without greenhouse gasses earth's average temperature would be well below zero. Water is actually by far the most important greenhouse gas.

Anything that absorbs infra red is a greenhouse gas.

Indeed a greenhouse effect is essential to life on earth; however, we are facing the enhanced greenhouse effect due to anthropogenic greenhouse gases. Anyway, before this becomes a huge off topic debate, the original post is quite interesting.
