Why is nitrogen important? | Nitrogen Footprint

Nitrogen (N2) makes up almost 80% of our atmosphere, but it is an unreactive form that is not accessible to us. Humans and most other species on earth require nitrogen in a “fixed,” reactive form. Reactive nitrogen is necessasry for the food production process.
