"Clear Blue Skies" Crosby Stills Nash, Album: American dream (1988)

Clear blue skies—not too much to ask for;
They were here before we came;
Will they be here when we're gone?

Clean water—not too much to hope for;
It's the basis of our lives,
And without it we are done.

Well, we can keep our eyes upon the skies
And see how the time goes by,
Or we can find our fears
Among the tears
That fall when the meadows cry, cry, cry . . .

Clear ideas—much too much to think of;
We need all the help we can get,
(And I know) we need all the time that we've got;
(And I know) we need all the love we can give . . .
It will be here when we're gone (clear blue skies)
It will be here when we're gone
Clear blue skies . . .

Wondering about the bad use of nature by humans, even when they pollute vital life sources like water.
