They're given weapons.

They shoot for the logging camps.

They get money.

Their culture is being destroyed, along with the animals upon whom they depend.

So when the logging camp moves, there's nothing left.

We talked already about the loss of human cultural diversity, and I've seen it happening with my own eyes.

And the grim picture in Africa, I love Africa.

And what do we see in Africa?

We see deforestation.

We see the desert spreading.

We see massive hunger.

We see disease.

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.

Were the people on the Easter Island who cut down their last tree, were they stupid?

Didn't they know what was happening?

Of course, but if you've seen the crippling poverty in some of these parts of the world, it isn't a question of, let's leave the tree for tomorrow.

How am I going to feed my family today?

Maybe I can get just a few dollars from this last tree, which will keep us going a little bit longer, and then we'll pray that something will happen to save us from the inevitable end.

So this is a pretty grim picture.

The one thing we have which makes us so different from chimpanzees or other living creatures is this sophisticated spoken language, a language with which we can tell children about things that aren't here.
