In the latter part of the 13th century, in an effort to stop
air pollution, England’s King I threatened Londoners with harsh consequences if they didn’t stop burning stuff However, the king’s regulations–and those of leaders–had little effect.
The Industrial Revolution began in Britain in 1700′s, and spread to the world, beginning with the United States. machinery and factories led to mass production, which in turn led to the rising of lots environmental hazards. The effects on the environment would only be seen clearly years later.
Along with technological, the Industrial Revolution of the 19th century introduced new sources of air pollution.The effects of these changes were beginning to be felt in countries around the world. Out of this movement came events like Earth Day, and victories like the Clean Air Act.
i think the more factories that we make and work in it just causes more air pollution in the world.
