The graph illustrates level of air pollution in America, China, Japan, Australia in 2011

Overall, China had the most polluted air while Australia’s asmostphere was generally the least polluted compared to other places. Additionally, electricity generation produced the lowest level of air pollution in all countries.

Industry production is the main reasons why China was polluted, at 88PPM which was double than the figure for Janpan and America, at over 40 PPM and 38 PPM respectively. The level of air pollution which caused by industry was the lowest in Australia, at over 80 PPM.

In term of transport, it created the highest in the level of air pollution in China, followed by America at nearly 70 and 50 PPM. The figures for Japan and Australia were much lower, at 30 and nearly 20 PPM respectively. While China had the level of air pollution which caused by electricity production was the highest at nearly 60PPM while 30,18 and 10PPM were released by this reason in America, Australia and Japan respectively
