2015 Isaac Asimov Memorial Debate: Water, Water

Earth is the only place in the solar system with liquid water on its surface. Where did this water come from? How much of it is drinkable, and how vulnerable is this valuable resource? Will wars of the future be fought over access to it? Will future generation harness water from space?

Our panel of experts included Heidi Hammel, Tess Russo, Ellen Stofran, Kathryn Sullivan, Charles Wald, and the debate was hosted and moderated by Neil deGrasse Tyson.
