Phosphorus and Nitrogen Cycles

Phosphorus and Nitrogen Cycles Although the effect of human activities on the carbon cycle is better known, influence on the Nitrogen cycle has a greater impact on the environment The use and abuse of nitrogen by the human race has resulted in a very beneficial technology for our species: every year, humans convert approximately 120 million tons of nitrogen from the atmosphere into reactive forms such as nitrates for the production of Fertilizers or food additives. Plantation residues reach the oceans and have a negative effect on phytoplankton, which is responsible for the production of much of the oxygen.
