Water, the New Frontier: Solutions Rethinking How We Use It

Global water use has increased sixfold in a century, and more than half the world's population now lives in a region that faces water scarcity for at least one month a year. On World Water Day it is worth remembering that water is not a side issue of the climate story. It is the climate story, arriving one tap and one harvest at a time. Several films in our library take it seriously.

Saving water at home

The most domestic example is also one of the smartest. Hydraloop is a refrigerator-sized device that recycles the grey water a household would otherwise flush away, cutting domestic consumption dramatically. It is proof that the biggest savings are sometimes hiding in the laundry room.

Harvesting and cleaning water in the wild

Elsewhere, the challenge is finding clean water at all. Drinking the Fog follows communities that capture drinking water from coastal mist using nothing but mesh and gravity, while Green Watech builds low-tech filters that clean wastewater in rural areas. Out at sea, the regenerative fish farm CascioMar shows that even aquaculture can help restore the water it depends on.

These are not luxuries for a distant future. They are working answers to a problem that is already here. To see the full collection, and the people behind each film, start on the solutions page or read more about us.
