The given table illustrates how much waste was produced in six major nations throughout a twenty-year period, starting from 1980 to 2000.
Overall, the US had the most significant amounts of pollution created across all the countries, whereas Ireland and Portugal were among the least. In addition, countries such as Korea and Ireland lacked of information in some points.
Regarding the first year, the US lead the list. Particularly, 131 million tones of waste was produced in the US in 1980, which was almost as much as five times of waste produced in Japan. By stark contrast, Poland and Portugal accounted for only 2 million tones and 4 million tones respectively. In terms of Korea, the information was not available, whereas Ireland had the least value at 0.6 million tones. In 1990, almost all the figures rose, except the Ireland, where the exact number was not listed. The figure for Japan increased to 32 million tones, and Korea reported quite similar number, with a difference of just 1 million tones. Interestingly, the figure for Portugal was higher than the one for Poland by 2 million tones, with the former staying at 5 million tones of waste.
Turning to the final year, all the reports were given clearly for each country. The US reached its peak at 192 million tones, while other countries were not close to this amount. Ireland and Portugal made up the same amount of 5 million tones, which was less than the amount of pollution produced in Poland by 1.6 million tones. Eventually, 53 million tones was released in Japan, while 19 million tones was created in Korea.
