"March 11, 2011, was three distinct disasters. The earthquake and tsunami fell into the category of tragedies that are often unavoidable.

Since the industrial revolution, there have always been industrial harms. As societies require more of technology, engineering, and transportation, there will be blips in the systems. What isn't inevitable, however, is that they happen again."
