Air pollution PPM level chart

Air pollution is a vital subject in our world. Whether in transportation or in industry, pollution is inevitable. Here in this chart, four countries and their PPM levels are shown. To begin with, it can be easily said that China is the leader among the other nations. With the PPM levels of 80 in industry, 70 in transportation and nearly 60 in electricity generation it is hard for people to breathe fresh air. Overpopulation may be the cause of these high numbers. On the other hand, Australia has the lowest in the two categories. It is interesting that these categories are almost equal in Australia as if they cannot be observed in the other three lands. Analyzing the remaining countries, there is almost a race between America and Japan. In transportation and electricity generation Japan is the winner in the terms of environmental protection. Especially in the latter, this nation has the most minimalized number. However, in industry, America turns the tables and prohibits the damages that this sector makes to our world by decreasing the pollution as Australia did. To sum up, fresh air is critical in our lives, on the contrary, none of the lands in the chart has decreased their PPM's to a more liveable world. These nations should consider climate change and its effects and make the environment a better place.
