Thanks for the info.

Some more green revolution problems.
* Pesticides are likely causing cancer. (Make sure you get enough Vitamin D. :-)
http://www.ncbi.nlm.nih.gov/pubmed/19523595
"It is projected that raising the minimum year-around serum 25(OH)D level to
40 to 60 ng/mL (100-150 nmol/L) would prevent approximately 58,000 new cases
of breast cancer and 49,000 new cases of colorectal cancer each year, and
three fourths of deaths from these diseases in the United States and Canada,
based on observational studies combined with a randomized trial. Such
intakes also are expected to reduce case-fatality rates of patients who have
breast, colorectal, or prostate cancer by half. There are no unreasonable
risks from intake of 2000 IU per day of vitamin D(3), or from a population
serum 25(OH)D level of 40 to 60 ng/mL. The time has arrived for nationally
coordinated action to substantially increase intake of vitamin D and calcium."
http://www.ncbi.nlm.nih.gov/pubmed/19269856
"Support for the UVB-vitamin D-cancer theory is now scientifically strong
enough to warrant use of vitamin D in cancer prevention, and as a component
of treatment"
I don't know about vitamin D deficiency in Africa or India. I imagine it
might be a problem for people moving to some cities and adopting an indoor
urban lifestyle? Could the entire (dark skinned) intelligentsia of Africa
and the Indian subcontinent be at risk of vitamin D deficiency?
As less people farm, and more people move to cities, do more people become
vitamin D deficient? Just speculation at this point...
* Many high-yield crops in terms of calories are often deficient in
micronutrients (as mentioned), and in some cases this has been so bad as to
cause serious problems, like birth defects and mental issues across wide
areas. And the problem is getting worse:
http://en.wikipedia.org/wiki/Micronutrient
"Micronutrient deficiencies are widespread. 50% of world cereal soils are
deficient in zinc and 30% of cultivated soils globally are deficient in
iron. Steady growth of crop yields during recent decades (in particular
through the Green Revolution) compounded the problem by progressively
depleting soil micronutrient pools. In general, farmers only apply
micronutrients when crops show deficiency symptoms, while micronutrient
deficiencies decrease yields before symptoms appear. Some common farming
practices (such as liming acid soils) contribute to widespread occurrence of
micronutrient deficiencies in crops by decreasing the availability of the
micronutrients present in the soil. Also, extensive use of glyphosate is
increasingly suspected to impair micronutrient uptake by crops, especially
with regard to manganese, iron and zinc."

Also:
"Let them eat micronutrients"
http://www.newsweek.com/id/160075
which misses the point that the soils have been destroyed by the Green
Revolution and other poor farming practices.
* The political power structure shifts towards more centralization of wealth.

We have discussed in Chapter 3, some of the effects of the Green Revolution
technology aids like new seeds, pesticides, fertilisers, excessive
irrigation, indiscriminating tapping of ground water resources, and so on.
This kind of technology requires more money just to get going and as a
result the large amounts required have led to a debt trap for the poorer
peasants. Those who find this technology economically viable are those with
medium and large farm holdings. A related issue is how today in India the
politics of agriculture and rural economy is one that is largely addressed
to the concerns of the richer farmers, thus further marginalizing the poorer
peasants, the landless and low income share croppers.
...
One of the major long-term consequences of the Green Revolution and of the
post-Green Revolution phase is the denial, neglect or lack of serious
debate about other modes of agricultural production or other methods of
agricultural knowledge practices. The Green Revolution culture is advertised
as the major model of ‘successful’ and ‘progressive’ agriculture. Wherever
such intensive large-scale deployment of technology and management has gone
in as in oil seeds or operation flood (for creating milk surpluses), often,
traditional, more sustainable forms of food production that guaranteed food
access to more of the poor tend to be overlooked. A feature that goes with
these intensive applications of technology is the incorporation of ordinary
food items like milk and oil as part of a centralized market economy with
little possibility of control or influence by actual users."
So, in the absence of a basic income, the Green Revolution may create food
insecurity where none existed before.
I could probably think of more issues if I tried. :-)
But overall, I believe in the power of technology to bring abundance. But it
needs to be the appropriate technology, with some sort of social equity, and
with continual montitoring and feedback about adverse impacts not a culture
of denial and vested interests. Openness is part of getting the least pain
from technology and the most benefit from it.
