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.
Two shocking events from last week unmasked eco-terrorists disguised as environmentalists:
1. The Philippines banned golden rice, condemning thousands of children to blindness and death 2. German Greens lied to closed nuclear plants
This is what happened and how to reverse it:
1. Golden Rice Ban
Golden Rice has added vitamin A over 100,000 children every year and turns blind over 100,000 more
Golden Rice has additional vitamin A, and eliminates that problem
But Greenpeace got a Filipino court to ban it. Why?
The court says "there's not enough evidence". But there is, proven by safety tests from countries like the US, Canada, and NZ. It is just like rice, except with more Vit A
You think housing prices will keep going up because you've seen it all your life. But this is a historic anomaly that is likely to reverse soon: Prices might start shrinking in many places.
This thread is the case against investing in housing:
Our perception of real estate prices is extremely biased.
Most ppl alive today have only experienced them since WW2, but that's a completely anomalous period!
Prices before did not grow as much. Here are real prices for 14 countries
What happened?
Supply and demand
The last 80 years have seen a growth of housing demand never seen before. At the same time, supply has been shrinking consistently. These trends are all reverting now. Let's look at them in detail:
Why do Jamaicans speak English, when most of its neighboring countries don’t?
Why was the pirate capital there?
Why is it underwater now?
Why did pirates drink rum?
Why are most Jamaicans black?
This map of shipping lanes today gives you a hint:
Jamaica is in the middle of all these shipping lanes, but isn't a major shipping hub today
This is not new: Back in Spanish colonial times, Jamaica was not in the main trade routes either
Spain's main goods were silver from Mexico and Peru and luxury goods from China
Spaniards gathered them in Panama, Portobello, Cartagena, and Veracruz
Ships arrived from Spain to Puerto Rico and left via Habana (Cuba)
Jamaica was not a main port
Why?
This machine makes fuel from thin air
It's carbon neutral
And it does this at record-low costs
Energy and the environment will look completely different in 10 years
Here's why: 🧵
The problem with fossil fuels today is not that we burn them, it's where they come from: They had been locked in the ground for millions of years and now they're back in the atmosphere. The pbm is the "fossil", not the "fuels"
If we make fuels out of thin air, we can burn them
How can we do it?
Natural gas is mostly methane (CH4)
You just need some energy to force some carbon (C) to bing to hydrogen (H)
Carbon can come from air (CO2)
Hydrogen can come from water (H2O)
The energy can come from the sun (solar panels)
This video of the Rock of Gibraltar gives an intuition for why some areas of the world have deserts next to rainforests
What's happening here?
How can you use that to predict where there will be deserts or rainforests?🧵
Look at the map below: In some places, deserts and lush forests are side by side. Why?
The mountain chains between them
The effect is called the Rain Shadow:
• Air comes wet from the sea
• As it hits mountains, it goes up
• Higher altitudes are cooler, so the air cools
• That condenses water (like the droplets on you Coke glass)
• Rain falls
• Air is dry past the mountains
Egyptian pyramids are not where they're supposed to be. Why?
Why is Cairo, the biggest African city, where it is today?
Alexandria?
Why do over 100M Egyptians live so densely clustered?
These questions all have the same answer. Look:
1st map: population density
2nd map: satellite
The "flower" is the inhabited part of Egypt, which is basically the Nile
It makes sense: outside of the Nile, Egypt is like the rest of the Sahara desert, an inhospitable hell for humans
