Blowin’ in the Wind

How many years will our forests exist

Before they end up in smoke?

How many years will our people exist

If they think the forest’s a joke?

Listen. How many crops will a desert produce?

And how much water to drink?

The answer, my friend, is blowin’ in the wind

The answer is blowin’ in the wind
