So, other than the build-up of salts in the Canadian and American grain
belts from over use of fertilizers, pesticides and irrigation
(accumulation of salts in the lowered water table) thus speeding toward
desertification, we have the added contribution of faster degradation of
the soils by bacterial digestion. It was always like pushing a boulder
up hill to get the farmers in S. Ontario to add more green manure to
their fields for healthier soils and better returns and (even more so
in the Mid west - I heard). So, I guess this can now be used by the oil
and chemical industries to tell the farmers not to do that. It will only
speed up global climate change. O, wait. Aren't they some of the biggest
deniers of global warming???
