Well, we've chosen these areas for maximum population density, so the ratio could be as high as 80 .

So we can do that. In fact in a densely populated country

And we're basically using mobility to get the access we need.

What's the country with the highest population density in the world?

This is Prickly Pear Creek.

And when the rain does come, it so often leads to flooding and added distress, and the cycle of poverty and hunger and disease.

Overcrowding

And it's an example of living and working together.

Or if we imagine the New York City metropolitan area, currently home to 12 million people, but 12 million people in the future, perhaps living at the density of Manhattan, in only 36 percent of the area, with the areas in between covered by farmland, covered by wetlands, covered by the marshes we need.

It's an area crowded with new houses.

So.

Australia and New Zealand.

The South East region of England is densely populated.

Japan has a high population density.

There are three population centers two here, and another on the northern continent.

It's just as fascinating as when I was a teenager.

And that can be done by raising the density in very specific spots a whole lot.

There are billion people in the world moving from poor to rich countries.

A vast military buildup of armoured divisions and missiles accompanied by a fourfold increase in the number of rocket bombs, directed at the most densely populated areas of Airstrip One...

The secret will remain locked in your mouth forever.

That's almost the size of Germany.

Let's go back and visit our equation.

The Silent and Secretive Pete Aron.

But the real puzzle and irony is that the greatest density of different languages on Earth is found where people are most tightly packed together.

let us consider the absolute numbers.

And they are helping each other solve these issues.

The evil has taken on the form of monstrous beings. That we have called... demons.

There's a backdoor into Prometheus.

It's one of the hundreds of favelas in Rio.

It's something of an Internet typology pattern, so you can have a series of these neighborhoods.

So, we believe that in those regions of the world where the population is large, and there's an infrastructure that can provide it, that a local, integrated, end to end system is really critical for its success.

And the message is, most countries are going to the right, and they're going up.

What you don't see on this map is that most of Russia's 150 million people are concentrated in its western provinces and areas that are close to Europe.

And I'm also a little nervous about this.

The crowd was moving in a solid body.

And exploiting that energy, human populations multiplied.

What we need instead is an average density that rises to a level where we don't drive as much and so on.

Something about the mouth of hell.

So, Zipcar is a company that I founded seven years ago, but it's an example of something called car sharing.

Ferro, take us in low over the main colony complex.

So to make matters even more difficult, it's a very young planet.

A recent survey reveals that the population density in the metropolis is decreasing.

So the white lines here are population.

Population

We see deforestation we see the desert spreading we see massive hunger we see disease and we see population growth in areas where there are more people living on a certain piece of land than the land can possibly support, and they're too poor to buy food from elsewhere.
