[casi] Water

[ 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."

~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.
