It's funny how there are only seven megacities south of the equator, but many more north.

Yes! I didnt focus on the fact that there some cities in the Northern hemisphere and I miss the 3 of them!

There are also very few megacities in the rest of the Americas, in the northern part of Africa, in Europe or the middle East

Well, there aren't many megacities in northern Africa because it's a giant desert and nobody wants to live there. Also, nobody wants to live in 120 degrees in the middle east.

North Africa’s population, outside of Egypt, mostly reside in Mediterranean climate zones, FYI. Morocco for one has barely anyone actually living in a hot desert area.

North Africa has large cities like Cairo, Alexandria, or Casablanca. Also, the hottest place in the world is death valley in America, and parts of the middle east are nice places to live.

I think the populations of countries in northern Africa and the Middle East might beg to differ on "nobody wants to live there"…

I think the fact that he expressed that temperature in Fahrenheit in a way that clearly expected the reader to intuitively understand that told us all we needed to know about how a) American and b) poorly-travelled he is...

That wasn’t really the focus, but I mean I think in this case it can be excused, as the comment was A) fairly obviously wrong and B) borderline rude to the populations of North Africa and the Middle East, as aforementioned…

Maybe it's because there is also more landmass in the northern hemisphere.

Yes. I don’t think people realize that ~70% of land is in the Northern Hemisphere, and that’s *including* Antarctica.

Obviously there are other Economic, Social, Politica, and Environmental reasons but the main reason is there is just less area.

Nearly 90% of earth's population live in the northern hemisphere...

Maybe cuz 70% of earths land is north of the equator and the southern hemisphere is mostly unninhabitable deserts or jungles with hot temperatures and tropical diseases making it hard for human life to develop

Nope. 10 million is almost half of Australia's population. It isn't possible.

But- Manila is FAR above the equator and likely would not make it. Not to mention the ENTIRE Philippines are above the equator and Manila is in Luzon, the most northern most significant island in the country.
