Nitrogen is an essential element for life sustenance. Scientists have been able to convert natural nitrogen into synthetic fertilizer for agricultural use. However, the excessive use of synthetic fertilizers has resulted in unintended consequences such as eutrophication in water bodies, loss of biodiversity, human illness, and an increase in ground-level ozone that contributes to significant environmental problems, including climate warming. The diagram illustrates the complex pathways of nitrogen transformation, highlighting both natural and artificial processes. It reveals how the overuse of synthetic fertilizers disrupts the delicate balance of the nitrogen cycle.
