AFP - More people die from unsafe water than from all forms of violence, including war, UN Secretary-General Ban Ki-moon said Monday in a message to mark World Water Day. 'These deaths are an affront to our common humanity, and undermine the efforts of many countries to achieve their development potential,' Ban said as the issue was discussed at a high-level UN General Assembly dialogue. 'Day after day, we pour millions of tons of untreated sewage and industrial and agricultural wastes into the world's water systems,' he said, noting that clean water has become scarce and would be even scarcer as a result of climate change.
