Why do people live in Namibia?

Why do people live in Namibia? I found this translation of the Südwester Lied on WikiAnswers: http://wiki.answers.com/Q/Why_do_people_live_in_namibia

There is a good German song about the place, 'Das Südwester Lied' (The Southwester Song). It says that it's a harsh place, with perennial rivers, the sun burning the rocks, and so on. Even although these happen, the people still love Namibia. This is because the sun also burns into the heart, and they can't go away.
The full song translated into English:
Harsh as Camelthorn wood is our country
And perennial are her rivers
The sun burns the rocks
And timid animals are in the bushes.

Chorus:
And should a man ask us:
What holds you here so firmly?
We would be allowed to merely say:
We love South West!

Though our love is dearly paid for
And for pride, we don't leave you
Because our caring nature shines above
The sun's bright, shining light.

Chorus:
And you seldom come to our country
And have seen very far -
And our sun has burnt you in the heart
Then you can't go any further again

And should a man ask you:
What holds you here so firmly?
You would be allowed to merely say:
I love South West!
