Water. It's the earth's most valuable resource. Our cities are powered by it, countless industries depend on it, and all living things need it to survive. But it's very possible that in the near future, there won't be enough to sustain life on our planet. From Academy Award®-winning director Jessica Yu (Breathing Lessons - The Life and Work of Mark O'Brien) and Academy Award®-nominated producer Elise Pearlstein (Food, Inc.) LAST CALL AT THE OASIS sheds light on the vital role water plays in our lives, exposes the defects in the current system, shows communities already struggling with its ill effects and introduces us to individuals who are championing revolutionary solutions, such as activist Erin Brockovich and distinguished experts Peter Gleick, Alex Prud'homme, Jay Famiglietti and Robert Glennon.
