1)Why do parents leave children at home??
Parents leave children alone at home is usually for convenience. They thought they will be right back in a short time that no accidents shall be occurred within such a short period.
2)Is it dangerous??why??
It is absolutely dangerous as you just can't imagine what a kid will do while not in the custody of an adult. Either climbing the window or playing with fire may result in a disaster.
3)What can be done to prevent this??
It has already been a criminal offence to leave children alone at home. To my opinion, education to parents is more efficient than punishment. As long as the parents are aware of the dangerous, they dare not to do it again.
