Humans do not require nitrogen, generally.
But nitrogen in the atmosphere is important to modify oxygen in the atmosphere. In the context of "too little" nitrogen in the atmosphere, the result can cause the ignition of almost every combustible on Earth, needing only a lightning strike to trigger it!
Worse for humanity, if nitrogen in the atmosphere dropped from its present (approx. 78%) ratio down to 67%, lightning in the atmosphere would create nitrous oxide, killing all humanity in minutes! Not to worry, though, long before that happened, the first calamity would already have occurred!
But feel better -
The most common usage of "too little" nitrogen is regarding soil. Too little nitrogen can turn green lawns into yellow. Nitrogen is the most important element in soil fertility, and is basic to chlorophyll, necessary for foliage (including trees) to create oxygen for us all.
