Nitrogen Footprint

Cal Poly Humboldt is also paying attention to its nitrogen footprint – the total amount of reactive nitrogen released to the environment as a result of resource consumption. Nitrogen is necessary in some form for all species on earth – however, when emitted in high concentrations, nitrogen can be a pollutant, causing smog, acid rain, dead zones, and other negative impacts to ecosystems and to human health. Fossil fuel combustion and food production are the two main ways nitrogen is released to the environment.
