Well you roll on roads over fresh green grass. 

For your lorry loads pumping petrol gas. 

And you make them long, and you make them tough. 

But they just go on and on, and it seems that you can’t get off. 

Oh, I know we’ve come a long way, 

We’re changing day to day, 

But tell me, where do the children play? /

Those were the lyrics of “where do the children play” by cat stevens.
