We haven't had a sustainable farm for 10,000 years. Those super fertile cradles of civilisation we learned about in school history lessons are just that - history,.The more you try to approach sustainable the less the farm produces. This is a bit of a problem in a world with 8 billion people.

That's the problem that remains unsolved for 10,000 years. Even if you reduce the number dramatically in one way or another, under favorable conditions it will start growing again resulting in the same overcrowded world.

A significant increase in efficiency for energy production and food production would both result in population increase. Yes. They do already explain the growth over the past 2 centuries. Whether the methods were "sustainable" is another story, but efficiency dramatically increased at this point in history, and the rest follows.

It's these feedback loops in nature which make me question a lot of proxy science like climatology.  If you put 0.000001% more emphasis on one feedback over another you end up with a very different answer.  What is actually happening is often hidden in plain sight too, but not seen until with hindsight.

While the population has been increasing over that time, the birth rate has been plummeting.  So it is not a social/biological positive feedback response.  We are responding with a negative stimulus on population.  The more energy and food the more time nations have to spend on education and enablement, which has a tendency to reduce family sizes, empowering women out of being baby factories and housewives [sic].

Population has been increasing primarily because 200 years ago infant mortality was about 85%.

A cursory search indicates that in the UK in 1820 (which wasn't so different to the rest of the world), the infant mortality rate was ~1/3 in 1800. You claim a 1/6 survival rate, whereas it was more like 4/6.

Even in worse places, it only reached 3/6.

I recommend you look at population vs food supply, water supply and sanitation. You will find a stronger correlation with population growth.

Try looking at the UK's population graph. It takes off after 1769, the year the first efficient steam engine was patented. Look at other countries, and you see a similar pattern. Efficient machines drove the population increase. Access to affordable energy drives all human development. Sure, hygiene and other factors were figured out in the boom that followed, and led to the situation we have today, but it all started with efficient machines releasing huge amounts of affordable energy.

Yes, or another way of looking at it is the production is no longer limited by muscle power.

And doomed slavery. Its no coincidence that 1769 is also the year that abolishionists started to get traction, or that abolishionist sentiments spread with the machines. Slavery is still a big deal, but not where there is advanced technology.

There is "modern slavery", unfortunately. It is not a well-defined term since there are many variants, but muscle power isn't the dominant theme.

Modern slavery is usually a term used for things like sex trafficking, but various industries, like chocolate production, are still (in)famous for a high use of good old traditional slavery.

Agreed, and to (try to) bring the conversation back to the topic title, probably mining metals - notoriously cobalt.

Most of that isn't actual slavery, although its not much better. Its appallingly paid work, with no control over working conditions. Some of the early industrial revolution in Europe was no better, but that wasn't referred to as slavery. On the other hand indentured servitude, which is often described as slavery, was seen as a step up, and a way out of those horrible conditions into a respectable trade. Isn't life complicated?

if you get those titanium tweezers, their like any other cheap tweezers. I needed to do a bit of bending so they line up (it was off by maybe 0.3mm) and I had to deburring pretty much everywhere (to make it nice instead of OK with a few NO)

the searations are.. rolled. Its not cut. Also requires some work with diamond files if you want it proper.

so its a good little DIY project to spend an hour on. But it should be fine for poking around in a plating beaker.

also, I wonder what kinda titanium was used in oceangate. They said they downgraded to grade 3. I wonder if they actually downgraded to counterfeit grade 3, you know.. to keep the QC racket at bay.

Yes, with mostly children. Not pretty.
