The diagram illustrates how the waste from production changed in Ireland, Japan, Korea, Poland, Portugal, and US between 1980 and 2000.
Overall, United States had the highest amount of waste in all years, whereas Ireland and Portugal had the least. In 20 years, waste production is noticed to increase in all places, except for Korea.
US remained as the most-polluted country over the years. If initially it had 131 millions of tonnes of waste, then in 2000 it reached almost 200 million tonnes. The country that had the smallest production waste was an Ireland only, having only over a half a million tones of waste; but after twenty years, Ireland and Portugal both had 5 million tones, which was the lowest number among all results reported.
From 1980 to 2000, all participant countries experienced a stable rise in the production waste and only Korea’s results had decreased. Specifically, Japan and US had 28 and 131 millions initally, after they reached 53 and 192 millions respectively. Meanwhile Poland rose from 4 to 6.6 millions of tonnes, Japan almost halved: starting by 28 millions and finishing with 53 millions. By contrast to these countries, Korea’s measurements fell from 31 millions in 1990 to 53 millions in 2000.
