Practically speaking.. (Score 1)

As disturbing (and academically interesting) as it is that plants help contribute to potential global warming in one way even as they relieve it to a moderate degree in another... does this really change how we deal with the warming problem that much? Practically speaking this mostly just discredits the positive role of plants in controlling CO2 emissions. The heart of the problem with our rising methane, etc. levels in the atmosphere comes from human industry and ruminant agriculture. A 10-30% methane contribution is indeed substantial, but would be environmentally sound if it weren't for all the other methane emissions we have at the moment. Even so, what can you do about it? Start reducing vegetation? If we're to actually work towards reducing methane levels, we have to start controlling human-related emissions. It's what we actually have control over and what is still apparently the most sizeable methane contribution.
