Quotes

 * Our water planet is not just rivers, lakes and oceans, but it's this vast network of groundwater that knits us all together. It's a shared resource from which we all drink. And when we can understand our human connections with our groundwater and all of our water resources on this planet, then we'll be working on the problem that's probably the most important issue of this century.
