More than 700 million people worldwide have trouble getting clean, safe water. That number comes from the Water Project, a non-profit group. It estimates that one in nine people does not have access to safe and clean drinking water. Governments, non-governmental organizations and charities sent representatives to Stockholm, Sweden, earlier this month for World Water Week activities. The subject for this year‟s water week campaign was “water and waste, reduce and reuse.”
