Explanation:
History of pollution. Although environmental pollution can be caused by natural events such as forest fires and active volcanoes, use of the word pollution generally implies that the contaminants have an anthropogenic source—that is, a source created by human activities
The way pollution can be defined has greatly varied in the course of history, according to times and places. It has long retained a moral and religious dimension. That some substances were “out of place” is attested since at least ancient civilisations. In France, as in most European countries, this pollution has been dealt with in the Middle Ages and in the early Modern period by removing dirt and dirt-producing activities onto the fringe of cities. This began to change at the end of the 18th century when states started to promote industry as a means of power. New pollutions also appeared with the birth of the modern chemical industry. But in the 20th century the scale of pollution changed dramatically: it became more intensive, with a growing number of pollutants discharged in the biosphere; more global, affecting all places on earth; more lasting, with disastrous cumulative effects.
