We rely on nitrogen.
ATP needs nitrogen, our DNA needs nitrogen, so it's essential to life as we know it.
And we think that it is as old as about 3 billion years.
So the first billion years of life didn't have biological fixation of nitrogen.
So what do we mean by that?
Luckily, there's a lot of nitrogen in the atmosphere.
But it is not readily available to our cells.
It cannot enter our cells as easily.
It needs to be transformed.
It's very, very strong.
So life invented it.
a way to break this bond and turn nitrogen into a form that is ammonia, that is available for life.
And that's been doing that for three billion years, relying on a single enzyme.
So if that enzyme is ruined, the whole show collapses.
So we created an artificial way of fixing nitrogen.
That's the Haber-Bosch process, which is insane amount of energy.
About 2% of world's entire energy consumption goes through the production of artificial ammonia through artificial nitrogen fixation process using Haber-Bosch.
