Planet Water

Water covers more than 70 percent of the planet's surface and represents more than 95 percent of its habitable space. Yet despite the enormous scale of our water world, we, humans, are having serious impacts. Yet there is still time to act. In this session, we'll discuss places where our actions have achieved measurable success.
