Against Child Abuse
For many children, child abuse happens in every day of our lives. A report from US government shows that over 2.9 million children encountered abuse in 2006. Approximately 1/3 of sexual abuse cases happened in children of young age, however, one in every four girls and one in every six boys were sexually abused by the age of 18. About 85% of sexual abuse happens with a person known to the child
However, most of children suffering abuse were threatened to keep silence or made to feel shame and guilt. These scars can deeply and long-lasting affect not only abused children, but also society.
There are four main types of child abuse, which are physical abuse, sexual abuse emotional abuse and neglect. Physical abuse and sexual abuse get the most attention, which accounting for more than 60 percent of all cases of child maltreatment. The signs of these 4types of abuse include:

Physical abuse:
Physical neglect:
Sexual abuse:
Emotional abuse:Our government also set strict law to publish abuser. In some country, like Singapore, even publishing children, the parents might be prosecuted by public. Every citizen has obligations report suspected child abuser. For example, if you see a child is being abused or neglected, call the police or your local child welfare agency.
Conclusion:

Child abuse is harm to a child for their growth, which can lead serious problem for the whole life. Although it is an international problem that tens of thousands of children suffer abuse each year. We believe that more children can grow in good environment according public’s help and publicity.
