10 POINTS TO BEST ANSWER !

Answer 1

Loss of commercially important fish stocks and ecosystems by promoting algal blooms, which result in oxygen deprivation and reduced sunlight in coastal and aquatic ecosystems.

Local extinction of terrestrial plant, animal, and microbial species, thereby reducing biodiversity and ecosystem health

An increase in the greenhouse gas nitrous oxide (N2O), which is contributing to global warming

An increase in the concentration of nitric oxide (NO), which contributes to acid rain and smog

Approximately 80% of Earth's atmosphere is nitrogen. However, only a small portion of this molecular nitrogen  is converted into a form that can be used by plants and animals.  This converted nitrogen is termed fixed nitrogen.  In the past this fixed notrogen was in a balanced amount of what was needed.  Unfortunately, industrial and other human-derived sources of fixed nitrogen have now doubled the rate that is now available.  This increase in fixed nitrogen has greatly contributed to the negative effects listed above.
