No elemental force has done more to shape life on this planet than water, from originating the earliest forms of life, to sculpting our landscapes, to determining patterns of human civilization. Humans have tried to control water for thousands of years, and access to this precious resource has caused conflict and also unlikely partnerships. In an era defined by climate disruption, the control, access, and quality of water will continue to determine our ability to survive and thrive. How can we ensure a future where clean water exists for all who need it and navigate the challenges of too little or too much?
