The student, concerned about water pollution, analyzed a pie chart depicting ocean pollutants' sources. To achieve the greatest reduction, focusing on sewage and farm runoff, which together contribute 50%, is crucial, surpassing other contributors like air pollutants, transportation, and industry waste.
The pie chart illustrates the distribution of pollutants entering the oceans, with various sources contributing different percentages. To achieve the most significant reduction in ocean pollutants, attention should be directed toward the most substantial contributors.
Sewage and farm runoff together account for 50% of the pollutants, making them the primary focus for effective mitigation measures. Addressing sewage treatment and implementing improved agricultural practices can lead to a substantial decrease in pollutants entering the oceans.
While other sources such as air pollutants, transportation, industry waste, offshore oil, and litter contribute to the issue, a strategic and prioritized approach would involve targeting the major contributors—sewage and farm runoff—for comprehensive environmental management and conservation efforts.
