Pulse investigates the inseparable bond between water and life. It reveals how a few drops of rain can cause deserts to bloom through a time-lapse sequence that took a decade to make, follows the journey of a molecule of water through trees in the Amazon to create giant rivers in the air and maps how the great animal migrations follow water around the planet.

But the world is changing. Drought-chasing scientists examine what happens when the pulse falters, showing how the flow of water is driven by its relationship with life. Show less
