The given graph illustrates the data and the comparison about the average proportion of four areas about the serious ecological issues was evaluated by some individuals in there, namely air polluttion, shortages of fresh water, automobile emissions, and climate change.
From an overall perspective, the trend of these problems is probably tried to reduce by the government, but over a period from 2000 to 2010 its effectiveness was still negligible. Especially, the issue of shortages of fresh water just appeard in 2001. However, all of these problems was not solve significantly by people in there.
Over the period from 2000 to 2006, plenty of fluctuations were recorded. Their severity began at a high rate, all started above 50%; 50%, 60%, and 70% respectively. In addition, through 2000 to 2003, and 2003 to 2006, it decreses, and increases considerably same. However, the issue of shortages of fresh water suddenly appeared in 2003 – the year that three other problems began increasing again. When the problem of shortages of fresh water appeard, it was immediately solved. This means when it appeared, it started to decrease the high percentage immediately.
Another part of the graph is 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 are 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.
