Oscar-winning documentarian Jessica Yu brings us Last Call at the Oasis, a documentary on the water crisis that’s happening throughout the world. Lakes, rivers and reservoirs are drying up, and water is more polluted than ever. This, obviously, spells trouble for every living human being. Interviewees include scientists and activists; one notable speaker is famed advocate Erin Brockovich-Ellis, who is a wealth of information on the contamination of water and the disastrous effects it can have. Probably the most-interesting topic is water-recycling. This has been done successfully, but the idea of drinking what was previously sewer water has been negatively received by those of us living in the U.S. This is an extremely in-depth, interesting and well-done documentary that deserves to be seen.
