I just stumbled upon the LifeStraw and loved the idea. Here are some
facts taken from the site.
"Half of the world's poor suffer from waterborne disease, and nearly
6,000 people - mainly children - die each day by consuming unsafe
drinking water.
LifeStraw® water purifiers have been developed as a practical way of
preventing disease and saving lives, as well as achieving the
Millennium Development Goal of reducing by one-half the proportion of
people without sustainable access to safe water by the year 2015.
LifeStraw® Personal and LifeStraw® Family are complimentary point-of-
use water filters - truly unique offerings from Vestergaard Frandsen
that will help people obtain safe drinking water at home and outside -
paving the way for swiftly and effectively accomplishing the VF and
MDGs."
