[ Presenting plain-text part of multi-format email ] Hello Tom and CASI, I recently came across an article that relates to a cheap and sustainable alternative to chemical water purification. This may be old hat for many of you but was new to me, so: "Crushed seed powder from the Moringa oleifera, a native tree of northern India, acts as a natural coagulant when mixed with water causing minute particles in the water, including bacteria and other microorganisms, to stick together and sink. The clean water can then be poured off. " Research on this was done by the University of Leicester. They said; "Our trials gave water purification results that were just as good as those obtained with commercial chemicals- at a fraction of the cost." Roger Stroope Northern Arizona University Flagstaff USA ~Just 10% of our military budget spent yearly on the United States could give every high school graduate a college education for four years. ~The proposed $48 billion increase in military spending for next year (2004) is bigger than the total military budget of any other country on earth. _______________________________________________ Sent via the discussion list of the Campaign Against Sanctions on Iraq.
