Pop. needs to fall back to ~1.7B as that's Earth's human natural carrying cap. - as determined by the pre-Haber Process natural Nitrogen pool. Vaclav Smil, SciAm, July 1997, 76–81. More relevant than ever. Synth. N is not a solution as is isotopically diff. and harms plant cell structure in our food.

This entire post is absurd.

There is no magic ‘carrying capacity’ number, except perhaps a couple hundred million before mechanized society and fossil fuels. And those times were far from pretty.

And synthetic fixed nitrogen is not isotopically different in some meaningful way. And even if it was, that isn’t damaging anything.

None of this content-free, rambling thread addresses major risks of motherhood. These include:

- death (giving birth is more dangerous than birth control or abortion)

- financial insecurity (can you get a job if you lose your co-parent?)

- hopelessness (many women don't want to bring a child into a world with existential issues like climate change)

And there are many more. Not a single one was addressed by this tweet.

These factors have always been present. If anything, they’re less of a concern now than they were historically.

If the most critical current issue for humanity is the climate and environmental crisis then we must accept that letting the population decline is also the most beneficial thing we can do for a sustainable solution.

Of course the problem there is that our whole economic system and thinking relies on an ever growing population. We have reached the limit of that on this planet but it is easier to refuse to accept it than to face the challenge head on.
