Based on June 2001: -And The Moon Be Still As Bright.

Ruin

This planet is too perfect for you or me

Feel awed by the impression the Martians left behind

Beautiful cities, clean land is all for to see

They knew right from wrong, unlike our kind

And now we come to wreak their lifework

Killing them off with our human diseases

All the good they did sinks into the murk

The nobility of their race ceases

It isn't enough to ruin our own world

We have to change theirs as well

Humans have not learned to leave things alone

But as the intentions of men unfurled

Their was one Martian left unknown

To hide Mars from men's destroying bombshells
