Like bank accounts, the nutrient cycles that influence the natural world are regulated by inputs and outputs. If a routine
withdrawal is overlooked, balance sheets become inaccurate. Over time, overlooked deductions can undermine our ability to
understand and manage ecological systems. Recent research has revealed an important, but seldom accounted for,
withdrawal in the global nitrogen cycle: commercial fisheries. Results highlight the role that fisheries play in removing nitrogen
from coastal oceans. [Source: NASA Earth Observatory]
