What's the meaning of the song blowing in the wind?

never heard of ti but who sings it?

I think most songs are, to a certain degree, open for interpretation. For me, the song is about asking the questions which are life's mysteries, and how the answer might be right in front of your face, but it can still take you forever to see it.

How many roads must a man walk down
Before you call him a man?
Yes, 'n' how many seas must a white dove sail
Before she sleeps in the sand?
Yes, 'n' how many times must the cannon balls fly
Before they're forever banned?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.

How many times must a man look up
Before he can see the sky?
Yes, 'n' how many ears must one man have
Before he can hear people cry?
Yes, 'n' how many deaths will it take till he knows
That too many people have died?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.

How many years can a mountain exist
Before it's washed to the sea?
Yes, 'n' how many years can some people exist
Before they're allowed to be free?
Yes, 'n' how many times can a man turn his head,
Pretending he just doesn't see?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.

the song is about peace, freedom and war. think about the civil rights movement, the viet nam war, kent state.
think about the war in iraq, how people are treated in this country and the world over, the homeless, the hungry...
think about all that and read the lyrics.
