     Across the world, 1.1 billion people have no access to clean drinking water. More than 2.5 billion people

lack basic sanitation.

     The combination proves deadly. Each year, diseases related to inadequate water and sanitation kill between

2 and 5 million people and cause an estimated 80 percent of all sicknesses in the developing world. Safe

drinking water is a precondition for health and the fight against child death rate, inequality between men and

women, and poverty.

     Consider these facts:

     The average distance that women in Africa and Asia walk to collect water is 6 kilometers.

     Only 58 percent of children in sub-Saharan Africa are drinking safe water, and only 37 percent of children

in South Asia have access to even a basic toilet.

     Each year in India alone, 73 million working days are lost to water-borne diseases.

     Here are three ways you can help:

     (1) Write Congress

     Current U. S. foreign aid for drinking water and sanitation budgets only one dollar per year per American

citizen. Few members of Congress have ever received a letter from voters about clean drinking water abroad.

     (2) Sponsor a project with a faith-based organization

     Many U.S. religious groups already sponsor water and sanitation projects, working with partner organizations

abroad. Simply putting a single project by a U.S. organization can make safe water a reality for thousands of

people.

     (3) Support nonprofit water organizations

     Numerous U.S.-based nonprofits work skillfully abroad in community-led projects related to drinking water

and sanitation. Like the sample of non-profits noted as follows, some organizations are large, other small-scale,

some operate worldwide, others are devoted to certain areas in Africa, Asia, or Latin America. Support them

generously.
