Hey Maddie ...
What's up JP?
I was just wondering ...
There's 7 1/2 billion people on Planet Earth.
Where do they all live?
Like houses or apartments or huts?
I was thinking more like geographically.
Ahh. Like China.
Yeah!
I think we could figure that out.
Let's do it.
You ready?
Yeah.
So what’d you find out?
So it turns out about half of the people on Earth live in just seven countries:
China, India, the United States, Indonesia, Brazil, Pakistan and Nigeria.
The U.S. has the third most people?
Yeah. It's big.
What about all the other countries?
All of 'em? There's like ... 190.
OK. Well let's simplify it. Maybe by continent?
OK. There’re seven of those too.
In North America, there's about half a billion people.
And South America, another half billion.
Europe has almost a billion. And Africa a little more than a billion.
And then there's Asia. With 4 1/2 billion people!
That’s more than half of the humans on Earth! On just one continent.
I think we can skip Antarctica and Australia. 'Cause they each have way less than a billion people.
So this is where all us 7.5 billion humans live.
That is a lot of humans! Especially considering 100 years ago there were less than 2 billion.
So how many more people will there be in the next 100 years?
The United Nations thinks that by about 2100, human population will actually stop growing.
They say more people will live in cities, make more money,
eat more food, get better health care, and have fewer kids.
By then, there will be about another half billion people in Asia.
And 3 billion more in Africa.
That’s 11 billion people on Planet Earth!
Eighty percent of us will live on just two continents.
Well, assuming nothing crazy happens.
Wait. Is that a space octopus?
Space octopus!
Nooooooooo!
