The two pie charts describe how different pollutants entered a specific segment of the ocean, percentage-wise in the years 1997 and 2007.
Overall, domestic sewage, offshore oil and air pollutants made up a significant increase in polluting the ocean whereas industrial waste, marine, litre and farm waste exhibited a substantial decline in polluting the part of the ocean. Notably, litre and farm waste had a tie in the beginning as well as domestic sewage and air pollutants at the end of the era.
Domestic sewage kicked off at 18% in 1997 then experienced the most significant increase ever recorded in 2007 of almost a third percent. Offshore oil also contributed the biggest part in polluting the segment of the ocean by increasing to 14% in 2007 from 5% in 1997. Air pollutants made up the least increment by 1% by the end of the period.
Industrial waste began at 17% and experienced a drastic fall by 8%in 2007. Marine which had contributed to 22% in 1997 dropped to nearly one fith percent in 2007. Apparently, litre had made up the lowest contribution in 1997 and in 2007, it deteriorated to a cipher, percentage-wise. Farm waste which comprised of 4% in 1997 fell to 2% after a 20 years period rendering it the pollutant with the least drop of all time.
