A thousand years ago there were only a third of a billion people.
Now there's 7 billion of us.
How did we grow so much so fast?
the fuller the glass gets the more people there are
Water drips in as people are born
water drips out as people die
a thousand years ago the Americas are nearly empty
better medicide and better agriculture are starting to slow the leak from the bottom of the glass
more babies gro up and have babies of their own
The UN says we'll level out at 10 billion by the end of the century
Can the world hold that many people?
Experts can't agree. It all depends on how well we manage our food, water and energy

BIG YELLOW TAXI - song
They paved paradise
And put up a parking lot
With a pink hotel, a boutique
And a swinging hot spot
[Chorus]
Don't it always seem to go
That you don't know what you've got
Till it's gone
They paved paradise
And put up a parking lot
They took all the trees
Put 'em in a tree museum
And they charged the people
A dollar and a half just to see 'em
Hey farmer farmer
Put away that DDT now
Give me spots on my apples
But leave me the birds and the bees
Please!
Late last night
I heard the screen door slam
And a big yellow taxi
Took away my old man
