In 1815, one billion people lived on Earth.

It took nearly 200.000 years for us to reach that first billion, and in just 200 we've added six billion more.

For that to happen, during the 20th century the world's population doubled, and then doubled again.

The planet adds one million people every four and a half days.

That's enough people to fill a new Dallas.

In less than 40 years we'll be sharing it with over two billion more.

That's two more Chinas and four more Americas.

How much more can we add?

How many people can the planet hold?

How can we tell if, in fact, we've already filled it up?

We have a choice.
