This bar grpath represent the air contamination cause by three different sectors in countries like China, America, Japan, and Australia.
Air pollution cause by Electricity generation, transport, and Industries is high in China compared to other countries.
Air pollution cause by Industry sector stands at 80 PPM in China and the lowest recording stabds at 16 PPM cause by power generation in Japan. In Australia, air contamination records between 17 to 19 PPM for all the three sectors and is less when compared to other countries. Unlike other countries, transportation is major cause of air pollution in America at 58 PPM. In Japan, the pollution cause by Industry is almost twice the pollution cause by Electricity generation, with highest standing at 43 PPM and lowest at 24 PPM.
Overall, air pollution in Australia is less by 3 folds when compared to China.
