The given graph illustrates the data and the comparison of the average proportion of four areas regarding serious ecological issues was evaluated by some individuals in there, namely air pollution, shortages of fresh water, automobile emissions, and climate change.
From an overall perspective, the trend of these problems was probably attempted to be reduced by the government, but over the period from 2000 to 2010, its effectiveness was still negligible. Especially, the issue of shortages of fresh water just appeard in 2001. However, none of these problems were solved significantly.
Over the period from 2000 to 2006, plenty of fluctuations were recorded. Their severity began at a high rate, all starting above 50%; 50%, 60%, and 70% respectively. In addition, from 2000 to 2003, and 2003 to 2006, it decresed, and increased considerably same. However, the issue of shortages of fresh water suddenly appeared in 2003–the year that the three other problems began increasing again. When the problem of shortages of fresh water appeared, it was immediately addressed. This means that when it appeared, it started to decrease the high percentage immediately.
Another part of the graph shows a period from the year 2006 to 2010. In 2006, all these issues began to fall out together. However, these problems increased again in 2007, while emissions from cars continued to fall, but overall, their increases and decreases were quite similar in this period. In addition, During the long period from 2006 to 2010, the improvement of these problems was not significant, because the severity of these pollutions in 2010 (the end of the graph) returned to the starting point-it was the same as before.
