The bar graph illustrates the amount of air pollution caused by electricity generation, transport, and industry sectors in four countries- China, America, Japan, Australia in 2021.
Overall, the majority of air pollution occurred in China. In America, transport is the main reason for this pollution. In comparison, pollution produced by all the three sectors is nearly same in Australia. now band?
In China, just below 60 PPM of air pollution was emitted from electricity generation and exact 70 PPM and 80 PPM affected by transport and industries, respectively. Similarly, in America, the amount of air pollution caused by electricity generation was just over 30 PPM, whereas air pollution from the transport system was almost twice that amount.
In contrast, Japan showed upward trend from electricity to industry sectors. Approximately 18 PPM of air was polluted by electricity generator, 30 PPM by transportation, and just above 40 PPM by the industrial sector. In Australia, just under 20 PPM of air pollution was contributed by all three sources.
