The charts shows air pollution levels by different causes among four countries in 2021.

The presented bar chart provides comparative analysis for air pollution rates among four main countries; through measuring levels in three sectors, which are electricity, transport and industry. It is worth noting that, through a bird-eye view, on average, manufacturing produces the largest amount of harms in the air compared to others. On the contrary, electricity production and transportation are considered the least, with almost equal impacts. It is pretty clear that in all the sectors, China has the highest percentages. Accordingly, this may reflect how the latest place ignores being environment-friendly by any means. Moreover, there are various companies, that belong to developed nations, focus on doing all damaging activities in the emergent ones. On the other hand, Australia is the best with the lowest percent in second and the third specializations; while Japan is a perfect location in the first one. To illustrate, Australia which acquires numerous natural reserves and parks; in addition, to its strict legal structure, have the cleanest climate. It is obvious that, throughout the graph, America and Japan are in the middle; however they still need to improve their efficiency more. To explain, it is significant to highlight that most of the time, both states apply a certain strategy, which is to do all risky actions in developing communities, putting it under the umbrella of investments. To conclude, civilization and technological innovations are not the main cause behind pollution; thus, they are not the major reasons and factors. Simply, the governments' focus is the thing that highly matters.
