Nuclear waste forces us to think about the distant future: the radioactive trail from our bombs and power plants will last 400 generations. Repeat: 400 generations! So we need a “deep time” contingency plan. How can we mark off toxic land to safeguard our descendants 10,000 years from now, when so little feels truly permanent? Part wake-up call, part observational documentary, part sci-fi graphic novel, Containment tracks our most imaginative attempts to plan for our radioactive future and reveals the startling failure to manage waste in the present, epitomized by the Fukushima disaster.
