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....
We (humans) don’t need atmospheric nitrogen to survive, we just need the “other” in the atmosphere to not be toxic. My guess is any element in the same periodic table column as nitrogen that could somehow exist as a gas at STP would be fine (hypothetically).
Don’t they replace nitrogen with like helium for some SCUBA applications?
Other life on Earth obviously does metabolize nitrogen (I think we do a little bit too). So to preserve our biosphere we should not throw off the nitrogen balance. But as others have observed it’s not clear there’s any imbalance coming.
As if alienation from our fellow humans is somehow a young male specific problem. The Internet and social media and smart phones are huge drivers to our alienation from one another.
So far he hasn’t fared well in front of judges he appointed either, with a couple exceptions.
For every question about things the Heritage Foundation has a strong evil opinion on, I’m sure that Heritage judges (appointed by Trump) will choose the evil answer.
But I don’t think Heritage wants to end American democracy. It’s worked out quite well for them. So I don’t think their judges (appointed by Trump) will rule in favor of ending American democracy.
Legalize racism? Sure, they’ll do that. Let a man try to overthrow our elections? Nah.
It’s gonna be middle managers and owners criticizing. The former because they add no value, the latter because… oh they add no value either, but they also profit off our work. But they’re afraid their lack of value adding will be discovered.
It’s possible that the N95 masks with their electrostatic charge might manage to intercept charged molecules but my chemistry is failing me as to whether NO2 or benzene would be affected.
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?

Would wearing a covid-style facemask while cooking significantly reduce the harmful effects of gas stoves?
Also, would it matter if it was the plain-style mask or n95?
