Re: water for food

Friends and Colleagues,

         I agree, the whole table looks suspicious. Perhaps, I should have
added a qualifier: "The data cited in this post have not been independently
verified (by me-maybe others have). The views expressed in the message are
not those of the messenger." I will, however, send a copy of this post to
the originator of the water for food post and give him a chance to reply. As
far as I can tell, the source of the data is a British Journal, but for all
I know, geez, maybe the figures are for livestock in the Sahel desert.
Perhaps sandy soils account for the spud figure, but I doubt it.

How about it SANnetters-does anyone have data to support or challenge the
"New Scientist" data?
