This report draws attention to the multiple benefits and threats of human nutrient use. It highlights how nitrogen and phosphorus fertilizers are estimated to feed half the human population alive today, and how they will remain critical in the future, especially given increasing population and potential bioenergy needs. Yet high nutrient use has created a web of pollution affecting the environment and human health, while insufficient access to nutrients has led to soil degradation, causing food insecurity and exacerbating loss of natural ecosystems. The report shows how these problems cross all global change challenges, threatening water, air and soil quality, climate balance, stratospheric ozone and biodiversity.
