An important message, I really like that you've written about this, and it's a decent poem. A couple of pointers - "But it’s that one who will decide," should it be "the one who will decide". To me that makes a little more sense and sounds a little better. Also using "ads" seems like a hard sounding word to use when used with all the others, and perhaps their is another medium you could use. Perhaps "television and music" would be good. These are just my suggestions though.
A good use of a final short stanza, I like that in poetry, it really ends a poem well and strengthens the overall message.
Good poem, important message, might need a couple of changes.
Remember this is just one poet's opinion. The next review might be entirely different.
