Summary Writing ： London’s Air Pollution

Air pollution was created from human activities. People use machines relying on industrial processes, which produce waste products. 700 years ago in England, people burned coal which produced smoke and soot. There was a tax placed on their use, but the air pollution did not improve. King Charles asked a scholar to research the problem in London, but the Industrial Revolution was about to begin. Consequently, people ignored the research report. After several years, London has many kinds of disasters from air pollution. People who can be high danger with heart and lung problems live there.
