It's just a big round rock, the only one there
Where people can live so we've got to share
All the space we've got, all the food we grow
All the air we breathe, and all the H-2-0
It's the last good planet in stock, it's just a big round rock

And it's my rock, your rock, everybody's rock
Rolling round the milky way
Yeah it's my rock, your rock, everybody's rock
We'd better treat it right and make it last another day

It's just a big round rock, we'd better start soon
If we mess up the earth, we'll have to move to the moon
It's just a little round rock with no room to grow
It's got no atmosphere and no H-2-0
The moon would be quite a shock
It's just a little round rock
We've got the best planet on the block
It's just a big round rock

But it's the last good planet in stock
So take care of our big round rock
