The given diagrams demonstrate the rate of different types of pollutants that contaminated a specific zone of the ocean in the time period between 19 97 and 2007.
From an overall perspective, the air pollutants along with domestic sewage were the primary reasons for ocean pollution, whilst, the role of the litter was insignificant.
In 1997, 30% of the total pollutants came from air then followed by marine, domestic sewage, as well as, industrial waste, which were, 20%, 18%, and 17%, separately. However, the farm waste together with litter and offshore oil were made a minor contribution to contaminate the ocean environment.
According to the second graph, the percentage of domestic waste showed a sharp increase from 18% to 29% of the total pollutants in 2007. Conversely, the marine, as well as industrial waste depicted a declining trend over the time period. It is interesting to notice that, in 2007 litter played no influence in an ocean whereas the impact of the farm waste was also faced a decrease. Though, the proportion of offshore oil presented a remarkable growth in 2007.
To sum up, the pollution from sewage and offshore oil had increased although there was a drop in other factors.
