Writing in the most recent issue of Frontiers in Ecology and the Environment, an international team of collaborators has described nitrogen (N) as "the largest pollution problem in coastal marine waters." Excessive amounts of N sometimes fuel blooms of algae that can outcompete or even poison other organisms, and evaporation of N into the atmosphere in the form of nitrous oxide can cause damage to our delicate ozone layer. Most of the nitrogen along our coasts is deposited there by rivers that pick up N-rich sewage, fertilizer runoff, and atmospheric deposits caused by the burning of fossil fuels; in other words, nitrogen is yet another form of anthropogenic pollution. read more
