“Daily life pollution” refers to the type of environmental contamination caused by the everyday life activities of ordinary citizens and consumers. In contrast to the pollution caused by industrial production processes, daily life pollution includes detergent pollution in rivers, lakes, or the ocean caused by washing clothes, and landfill and incineration pollution caused by excessive household garbage. Although the individual impact each citizen has on the environment is negligible, cumulatively their behavior can create severe environmental and social problems. This cumulative effect resembles the old proverb, “Many drops make a flood.” Theoretically, “the tragedy of the commons” and the subsequent studies of the “social dilemma” neatly model this mechanism. In many cases of daily life pollution, the effects appear directly and visibly for ordinary citizens within a relatively limited geographic range. Current issues of climate change and ocean plastic waste are examples of the worldwide effects that will affect future generations.
