Researchers form Brown University and Washington University found that nitrogen isotopes ratios have changed significantly in the past 300 years, especially between 1950 and 1985. They believe that this change in the nitrogen cycle is caused by the increased combustion of fossil fuels, which has greatly increased in the past 60 years. Introducing this new source of nitrogen to its cycle has greatly increased the nitrogen stored in the atmosphere. This is a problem because the released nitric oxide binds with other elements  and forms smog and acid rain which affect multiple environments. Also, the increase of nitrogen in the atmosphere has effected lake chemistry by causing organic nitrogen decline. Is it possible for these changes to be reversed?
