The given bar graph compares the number of pollutants in the air of four nations China, America, Japan and Australia with their causes in 2021. Overall, we can see that China has the highest level of air pollution whereas Australia has the lowest. Most of the air pollution is produced from factory waste in China and Japan as opposed to transporting in the US and electricity in Australia in the current year. Industrial waste is the highest contributor to air contamination in China and Japan at 80 and 42 PPM respectively. Both of these countries have a similar looking graphs where their highest contributor is industries, followed by transport at 70 MPM and 30 MPM and lastly by electricity production at 60 MPM and 15 MPM. While in America more air pollution is produced from traffic than other sources at 60 MPM, Australia has almost the same level of contribution from every factor at almost 10 to 20 MPM, where electricity seems to have slightly higher contribution. However, America and Austaralia comparatively have less contribution from industries at 30 MPM and 29 MPM respectively.
