"""food activity - kind of EnergyBeing (http://an.org/programming/being.py),
   to study food production, distribution and use,

   TheRealWorld IsA FoodWorld,
   shouldn't we get rid of AbsolutePoverty ?   
   http://en.wikipedia.org/wiki/Poverty_line#Absolute_poverty

   This work was inspired by the movie The girl in the cafe
   , )http://www.thegirlinthecafe.com/
   featuring the G8 group and their Millennium programme.
   .. saw it from tv the day before yesterday,
      and talked about it with my wife yestarday,
      and got inspired by it to work on so that started today.

    11:52 < [Infinity]> Yes! Like the war games the government does to conquer virtual
                    threats to the country!
11:52 < antont> referring again to the prob that even with money it is not easy to
                make good things happen
11:52 < antont> right!
11:52 < [Infinity]> However they actually had a wargame about something like Katrina
                    a few onths before it hit... And did it help?
11:52 < [Infinity]> months*
11:53 < [Infinity]> It may have helped a bit... Personally i htink that the entire
                    tradgedy was the fault of stubborn floridans.
11:53 < [Infinity]> think*
11:53 < antont> also with the non-trivial structures we now have in place .. like
                that european kingdoms took gold and diamonds from africa and are
                rich, poor countries owe money to them, so they must grow coffee and
                tobacco that they can sell to europe to get money to pay the loan
                interest, so they can't grow food for themselves
11:54 < antont> actuall test_farmer() is the function i've been thinking of writing
                next, that 'whether to grow tobacco or food' decision :)
