Sexually exploited. Recruited into armies. Shut away in institutions. These are the biggest and most dangerous things children in the world get in to. I'm not saying we should ignore it, i'm saying that it is probably too late for these children to look out for or keep an eye on.

Millions of children around the world are in danger of abuse, neglect, exploitation and violence at home, in school, etc... families/parents that are outside dangerous areas that are living their lives at the fullest, they can make this happen at any time. Abuse your children their lives will turn upside down just like that, neglect them they will surely be uncontrollable and as soon as you realize it, you will be too late to stop them from whatever they are in, it's either drugs or gangs, exploitation or child sexual exploitation children in exploitative situations and relationships receive something such as gifts, money or affection as a result of performing sexual activities or others performing sexual activities on them, and the most common would be home or school violence for home it would be an abusive family, specially fathers that drinks a lot, for school it would be bullying but most bullying occurs nowadays are done online because of us being over run by technology. Being bullied on the internet will last forever because it spread like wildfire. 

My point for the first part is that, those three things should be a wake up call for parents a warning that is for parent to really protect their children because for those children their parents are already too late. As for the second part Parents that are with their children or upcoming children they can prevent this all from happening just by really keeping an eye on their children, keep an eye on their safety.
