The combustion of fossil fuels is a large human-initiated contributor to atmospheric nitrogen pollution.

Still, studies have shown that the effects of atmospheric nitrogen pollution can reach far past the buffer zone.

As the human population increases and more of the world develops, consumption of animal products increases and the associated nitrogen pollution poses substantial threats to the environment.

Unless nitrogen pollution is significantly reduced, many of the rare plants for which conservation sites were designated or nature reserves were set up will disappear.

HSG studies in Europe and New Zealand, for example, reported a reduction in nitrogen pollution by as much as 24 percent.

Mud pollution has increased by 800% and inorganic nitrogen pollution by 3,000% since the introduction of European farming practices on the Australian landscape.

Jeanette Brown is working hard to reduce the amount of nitrogen pollution into Long Island Sound.

But he says he is convinced that the almost explosive growth of the lilies is proof of the nitrogen pollution they have helped avert.

The explosive growth in the production of ethanol as a biofuel is greatly aggravating nitrogen pollution.

The reason is that much of the nitrogen pollution comes from non-point sources in agriculture, and the still insufficient nutrient removal by wastewater treatment plants.
