The geography of Egypt is bonkers 🇪🇬🌍
Look at that image of the Middle-East by night. See that "flower" in the middle? That is the Nile.
Egypt has 105 MILLION ppl!
99% of them live in that light area!
That's 3% of its territory!
What else is crazy about Egypt's geography?
🧵
The Nile's banks are between 0.5km and 20km wide (~0.3 to 12 miles). 105M ppl live in that area plus the delta. Crazy. They do that because it's fertile AF
What's outside though? Nothing.
In the west, there's nothing for thousands of miles. There's so much nothing that in 5000 years of history, Egypt has NEVER been successfully invaded from here.
Look at the south. The lights stop abruptly. Why? Does the Nile stop there? Not at all. It continues for thousands of miles. What then?
The Aswan Dam
The Aswan Dam has created a huge lake. The southern border of Egypt goes through that lake, quite close to the dam.
Isn't that weird? Why is the same point a dam, a border, and the limit of lights and population of a country that packs 105M ppl in such a small place?
Cataracts
See, the Nile flows very slowly across all of Egypt. But not before. Aswan is where the Nile's 1st cataract was. Then there are a bunch more upstream.
Really, Egypt's length was defined by the place of a cataract.
What do they look like?
Nothing crazy. They're just points where water is faster, rocks appear on the surface, and some banks of sand might accumulate.
What's the big deal then?
This is where the Nile is not navigable anymore.
So Egypt couldn't easily incorporate it into their empire.
Different kingdoms appeared over time. That area to the south was called Nubia.
Egypt & Nubia mixed over millennia, but still remained different enough that that area to the south is a different country, Sudan
The banks of the Nile there are narrower.
Between the narrower banks, the faster flow, and the fact that it's not navigable, Sudan is much poorer and has a smaller population. They can't even afford as much electricity as Egypt—which is partially why the lights stop at Aswan
What's in the north? The delta
It's beautiful.
You know what it's not? Navigable.
40% of the population and 50% of the crops come from there, but the Nile spreads so much that trade ships can't navigate.
That means that, despite being the oldest civilization on the Mediterranean, Egypt was never a naval power.
It's not just that the Nile can't be navigated. It's also that Egypt has no room for trees. No trees, no wood, no ships, no trade, no navy.
Poor and exposed.
If you were clever, where would you put your capital in such a country?
Pharaohs had thousands of years to think about it, and usually picked the point between the delta and the Nile proper.
That's Cairo today.
And funnily the Suez Canal is a stone throw's away from there.
Big deal, because the Suez Canal accounts for a huge share of Egypt's foreign currency.
How did this influence its history?
The pharaohs?
Why was Egypt invaded so many times?
Why is it poor?
Why is it friendly with Israel?
With the US?
Why the military pushed aside the Muslim Brotherhood?
It all comes down to geography.
2. Los Angeles:
• Trading hub between the world (Pacific) and the US (railways)
• Weather + biggest coastal valley on the Pacific➡️agriculture & cheap building
• Oil
• Landscapes + far from the East Coast centers of power➡️Attracted the film industry
People think we must shrink the world's population to be happy, but they're wrong
A world with shrinking population would be decaying, poor, brutal, violent, hopeless
A world with 100 billion people would be dynamic, rich, innovative, peaceful, hopeful

1. In the last 2 centuries, the world got better as the population exploded:
• Richer
• Live older
• Lower child mortality
• Fewer homicides
• Fewer war deaths
• Fewer hours worked
• Lower share of poor people
And much more: fewer infections, diseases, accidents. More racial equality, sexual equality. Instant access to all the knowledge in the world. We can go anywhere, whenever we want...
We can raise our population on Earth from 8 billion to 100B humans if we want to
Would we starve?
Be too crowded?
Would pollution explode?
Ecosystems collapse?
No! Don't believe alarmist degrowthers. This is why they're wrong: 🧵
Degrowthers put a label to "how many humans can the Earth sustain": carrying capacity
Their estimates vary wildly
Wait, what? What a surprise, the mode of their estimates is 8B—exactly the current number of ppl on Earth
WHAT A COINCIDENCE!
Or they lack imagination: OMG the Earth is already on the brink. Surely not one more soul fits here!
And then they try to find out what limits we might be hitting. Their most common fears are: 1. Room 2. Food 3. Water 4. Energy 5. Pollution 6. Resources
Let's look at each:
Can desalinated water deliver a future of infinite water?
Yes!
• It's cheap
• It will get even cheaper
• Limited pollution
• Some countries already live off of it
We can transform deserts into paradise. And some countries are already on that path:🧵
Crazy fact:
Over half of Israel's freshwater is desalinated from the Mediterranean!
And the vast majority of its tap water is desalinated too!
And it costs less than municipal water in a city like LA!
It's not the only country. Saudi Arabia is the biggest desalinator in the world. 50% of its drinking water is desalinated. It's 30% in Singapore, a majority of water in the UAE...
What if we applied this, but at scale across the world?
President-elect @realDonaldTrump could own the environmentalists by solving global warming on his first day in office, and do it for 0.1% of current climate investments

1. GLOBAL WARMING
2024 is the 1st year we pass 1.5ºC above pre-industrial levels
This is caused by CO2
Some side-effects of this CO2 are good, but it's undeniable that the planet is warming fast, and it could create some nasty pbms

Beata Halassy got cancer in 2016, then again in 2018, and again in 2020. That looked awfully bad. She knew if she continued in the traditional route, her cancer might eventually prevail. So she decided to try what she knew about: viruses
Here's the theory: 1. Select a virus that is likely to attack your target cancer cells 2. Because cancer cells neutralize the immune system, they're more likely to be killed by viruses than healthy cells
