The two pie charts show the percentage of pollutants entering a particular part of 
ocean in 1997 and 2007. Summarize the information by selecting and reporting the 
main features, and make comparisons where relevant. 
The two pie charts give information about the percentage of pollutants that entered a specific 
section of ocean in 1997 and 2007. 
The quantity of domestic sewage entering the ocean increased significantly, from 18 percent 
to 29 percent, during the ten-year period. The pollutants from air were approximately the 
same at about 30 percent in both the given years. 14 per cent of pollution was from offshore 
oil in 2007, which was about three times the figure, a decade ago.
By contrast, industrial waste and marine saw a fall of 8 percent and 5 percent during this 
period. The pollution from litter accounted for 4 percent in 1997. However, it is interesting 
to note that there was no litter in this part of ocean in 2007. The amount of pollutants from 
farm waste declined from 4% to 2% in ten years time.
Overall, the pollution from domestic sewage and offshore oil increased, while there was a 
drop in the amount of other pollution.
