Water for Life
Water is essential for life. Yet many millions of people around the world face a water 1 (short). Many millions of children die every year from water-borne di 2 and drought regularly afflicts some of the world’s poorest countries. The world needs to respond. 3 more effectively.


We need to increase water efficiency, especially in agriculture. We need to free women and girls from the daily chore of 4 (get) water, often from great distances. We must involve them in a decision about water management. We need to make sanitation a priority. This is 5 progress is lagging (滞后) most. We must also show that water resources need not be a source of conflict. Ins 6 , they should be a catalyst (催化剂) for cooperation. Significant gains have been made, but a major ef 7 is still required. That is why this year marks the beginning of the "Water for Life" Decade. Our g 8 is to meet the internationally agreed targets for water and sanitation by 2015, and to build a foundation for 9 fur progress in the years ahead.
This is an urgent matter affecting human 10 (develop), and human dignity. Water for Life
