Why are we so concerned with oxygen production yet we never hear about nitrogen production, though we actually need 78% nitrogen vs 21% oxygen to survive?

Excess oxygen is actually harmful to humans, but all the climate warnings are about losing oxygen, not nitrogen edit: but when we look for habitable planets, our focus is ‘oxygen rich atmosphere’, not ‘nitrogen rich’, and in medical settings, we’re always concerned about low oxygen, not nitrogen....

The girls co-opted my meditation pillow last night. It took me like 15 ‘minutes of glacial creeping to get this shot, and Precious still looks suspicious, but score! ( i.imgur.com )

They’re both semi-feral and don’t always get along. Precious (the calico) doesn’t often have patience with her daughter, and Moppy (the big one) spooks at everything, real or imagined. I’ll never get another picture like this, so had to share.
