Water is being depleted many, many times faster than nature can replenish it.

No piecemeal solution is going to prevent the collapse of whole societies and ecosystems ... a radical re-thinking of our values, priorities and political systems is urgent.

Robert Glennon is a leading-edge legal scholar and passionate water advocate whose thinking is central to an intense debate on the path forward to a water-secure world. I heartily recommend his provocative, information-packed, and highly readable new book Unquenchable.

We are committed with our lives to building a different model and a different future for humanity, the Earth, and other species. We have envisaged a moral alternative to economic globalization and we will not rest until we see it realized.

The destruction of aquatic ecosystem health, and the increasing water scarcity, are in my opinion the most pressing environmental problems facing human kind.

There is simply no way to overstate the water crisis of the planet today.
