[Marxism] Are belching cows really driving climate change?

The article is about soil carbon. Without it there is not much excuse for
active plant life to be had nor means to retain moisture.
Here in  Australia, soil carbon levels have dropped by up to half of
pre-agricultural levels in many areas because of activities such as
cultivation, stubble burning or removal and overgrazing.
Worldwide,  cultivated soils have maybe  lost between 50 and 70 percent of
their original carbon stock.
A good place to start thinking about soil carbon and sustainable
agriculture practices of a region  is to monitor SOC (or SOM) -- Soil
Organic Carbon -- levels in the soil.

Here's what the journal 'Nature' says about carbon in soils:

"The amount of C in soil represents a substantial portion of the carbon
found in terrestrial ecosystems of the planet. Total C in terrestrial
ecosystems is approximately 3170 gigatons (GT; 1 GT = 1 petagram = 1
billion metric tons). Of this amount, nearly 80% (2500 GT) is found in soil
(Lal 2008). Soil carbon can be either organic (1550 GT) or inorganic carbon
(950 GT). The latter consists of elemental carbon and carbonate materials
such as calcite, dolomite, and gypsum (Lal 2004). The amount of carbon
found in living plants and animals is comparatively small relative to that
found in soil (560 GT). The soil carbon pool is approximately 3.1 times
larger than the atmospheric pool of 800 GT (Oelkers & Cole 2008). Only the
ocean has a larger carbon pool, at about 38,400 GT of C, mostly in
inorganic forms (Houghton 2007)."

As the GLW article points out, there is a perverted discussion being
sponsored about the ecology of carbon as it is biased towards reductionism.
