III. Need for investment and education
Water treatment and distribution systems can be costly to install and maintain, but these costs need to be assessed relative to the extensive hardship experienced by those without these services. There is clearly a role for the developed world to play here, both in terms of investment and education.
Current State of the Clean Water Challenge
"The failure to provide safe drinking water and adequate sanitation services to all people is
perhaps the greatest development failure of the 20th century. The most egregious
consequence of this failure is the high rate of mortality among young children from
preventable water-related diseases." (Peter H. Gleick, Pacific Institute)
World Maps - a wide-spread problem
Insufficient access to clean, safe drinking water is experienced across the world - but it is particularly focused in lesser developed countries. This is illustrated in the map below.
