this pie chart analysts proportions of different types of contaminants discharging in a specific area of ocean in 1997 and 2007.
It is clear that in 1997, the amount of trash are in the majority and the figure of air pollution was the lowest. However, in 2007, most of pollutants are oil whereas the minority was agricultural runoff.
In 1997, trash is the most popular type of contaminant, at 42% but the figure of trash dropped nearly threefold to 15% in 2007. Comparatively, there was only 15% of oil in this area in 1997 then there was a significant increase in the percentage of oil, at 52% and become the largest amount of pollutant at the same time.
The figure of air pollution was only 3% and was the lowest rate in 1997. Meanwhile the data about sewage and agricultural runoff are 15% and 25% respectively. In 2007, the percentage of air pollution rose more than five times, at 15%. By contrast, both the figures of agricultural runoff and sewage decreased to 10% or below.
