Water is the most critical resource issue of our
lifetime and our childrens lifetime. The health
of our waters is the principal measure of how we
live on the land.
Luna Leopold
When we save a river, we save a major part of an
ecosystem, and we save ourselves as well because
of our dependence physical, economic, spiritual
on the water and its community of life.
