Humans use energy.
Production of both food and energy increases the amount of biologically active nitrogen that circulates among the world's atmosphere, soils, forests, and waters. Building on Results. The First International Nitrogen Conference was held in The Netherlands in March 1998. A consensus view was developed. Aquatic and terrestrial ecologists, marine biologists, agricultural scientists, meteorologists, climatologists, atmospheric chemists and physicists, and biogeochemists realized that dealing with oxidized and reduced forms of biologically active nitrogen separately was no longer tenable scientifically.
