Eugene Smith's Minamata Disease explains the efficacy of documentary photography.

Let the masses know about Minamata disease and expose the facts.

1, let people know about Minamata disease. His photographs recorded the fatal impact of mercury pollution on Minamata Bay, Japan. For many years, Japanese chemical company Chisso has been discharging excessive mercury in its chemical plant in Minamata Bay, which directly led to thousands of mercury poisoning incidents, namely Minamata disease.

2. Expose the facts. It was not until 1968 that the government finally issued a statement officially acknowledging that Minamata disease is a disease caused by industrial pollution.
