And understand its interactions with the entire Earth.

With regard to the biogeographic question, the Earth is dividing.

This pixel is the Earth.

I want to spend most of my time on this part of the world.

One of the selection points is not on the Globe. Please only select a region on the globe.

There is a great deal of talk today about life in the global village.

It's nearly halfway around the globe.

This, of course, is a map of the moon.

In this world, the good earth is rich and can provide for everyone.

Imagine that that Earth is at the center of the universe, and surrounding it is the sky projected onto a sphere.

And then this is the first part of this is 109 spheres, since the Sun is 109 times the diameter of the Earth.

Again, you know, mental, visual, 10 planets, one planet, 10 planets, one planet. Right?

Imagine you're learning to play tennis and you want to decide where the ball is going to bounce as it comes over the net towards you.

One of the best places in the world to see blue whales is here in this region.

So this, again, is on the subject a slice from the equator of the Earth.

I know this may come as a great big shock to the both of you... but underneath all this hair and skin is a human girl.

The world is ball with stick through it.

Because to find a place like this today on Earth is really very, very challenging.

I'm developing the means to destroy this planet when I decide to move to another one.

And to end all of this, at the end of this long process, we're not even managing to feed the planet properly.

All my life i've been waiting for this, it's... it's a pocket hanger.

It passed directly through Earth's orbit. We were in that that spot six hours earlier.

Which is actually the north pole of the magnet we call Earth.

Now the situation in the world is going to change for you and me, for everyone on this Earth.

And on Earth Day, 1990 the 20th anniversary of Earth Day that s when I began to speak.

We're already an urban planet that's especially true in the developed world.

It's not really that foreign of a concept, actually it happens on the Earth every day.

They're taking information from our planet at very critical places like Antarctica and the Poles.

Up until recently, that was the Solar System four Earth like planets with small radius, smaller than about two times the size of the Earth and that was of course Mercury, Venus, Mars, and of course the Earth, and then the two big, giant planets.

The fire gave way, Earth emerged but this was an alien planet.

Coming in closer, picking up Earth, orbit of the Moon, and we see the Earth.

We don't have that. So that's one problem.

It concerns the existence of every last creature on Earth.

Now, what you're having here is basically a global brain that you're able to do lots of kind of experiments on to see what it's thinking.

It's during our lifetime that we're going to take the Earth, take the people of Earth and transition off, permanently. And that's exciting.

There was a tennis court... or rather the ghost of a tennis court... with faded markings and a sagging net.

There is no place left that is immune.

The equator divides the globe into two hemispheres.

Still, in this place, in this grassland where you can see our very first office there on that hill, four years later, there is this one green blop on the Earth's surface ...

That may be because those events were occurring on the other side of the world where nobody was paying attention.

Nowadays this idea has a dramatic name Spaceship Earth.

That is what we have done on this planet.

This is not on another planet. These are things that are hidden away on our planet.

And so we're on one planet, and we have to be able to get to the root of these problems.

And it was the first time we had ever seen from another surface that's the place where you and I are right now, where we live.
