How water arrived on Earth, and how it became the essential force behind all life -- from dragonflies to humans.
How water may have driven the evolution of man and created the earliest civilizations; whether the Earth's water supplies can guarantee the future of humans.
Earth's changing water cycle, and the globalized movement toward water for profit, forces changes across the globe with regard to people's reliance on water.
