Hi Orla,
Yes, that is very true, children should not be travelling great distances on their own. On the other hand every culture have their own way for raising children. Parents are aware of children being mugged, attacked and abducted, but it is due to their negligence as parents that they choose to put children in harm's way. As observers, we cannot tell parents how to raise their children.
The refugees from the Ukraniain war will definitely suffer from the scars of war and will not be able to rebuild their lives. The trauma of war will have devastating effects on all of them.
Changing the world is not in our hands, but in the hands of those who rule our world. we may have alll the ideas and the opinions but at the end of the day we cannot make major changes to the way in which society works. Wriiters make gradual changes in the minds of people, but it is a rather slow process.
