The two pie charts compare the percentage of pollutants entering a particular part of the ocean from 1997 to 2007.
Overall, it is clear that the maximum proportion of pollutants was air. While the domestic sewage, offshore oil and marine were increased and the pollutants of litter, farm waste and industrial waste were decreased in a given time period.
In detail, in the 1997, the percentage of pollutants from air was 30 percent. The domestic sewage was 18 percent and the offshore oil, marine were 5 percent and 8 percent. Whereas, the pollutants in litter and farm waste were the same at 4 percent and industrial waste was 17 percent.
By contrast, in the 2007, the pollutants from air was almost the same at 29 percent and the domestic waste was sharply increased and reached a 29 percent. The offshore oil and marine were increased of14 percent and 17 percent. The litter was showed 0 percent and farm waste, industrial waste both were decreased of 2 percent and 9 percent in the ten years.
