In the past there have petitions for wills, sgk, animals and whatever.
Personally I don't think that those petitions made any difference.
But the person who signed the petitions probably felt that he/she was able to do "something".
There isn't much we can do about the atrocities that are happening in Syria but we can at least show our feelings about it.
Hundreds of children have died because of the chemicals used.
When will the world open its eyes?!?
