Water must be maintained as a human right and a common good.

Here's a site we like alot: www.kairoscanada.org.

And here is the link to their water page: http://www.kairoscanada.org/e/ecology/water/index.asp.

KAIROS unites churches and religious organizations in a faithful ecumenical response to the call to "do justice, and to love kindness and to walk humbly with your God" (Micah 6:8). We deliberate on issues of common concern, advocate for social change and join with people of faith and goodwill in action for social transformation.

This site is full of great material for anyone interested in the intersection between spirituality, social concern and action for the common good. Canada based, but most of their work is applicable anywhere.
