Stop underage pornagraphy and pornagraphy being so easy to see through, television, phones, computers and R rated movies

To stop children from being used to promote any type of cellphones, computers (putting their own pictures) sexual acting role, picture taking, take part in movie, advertisements, cartoons, toys(. For example Barbie dolls),TV or any commercial, on and on, I have seen, while trying to find something appropriate to watch on TV,to many children to young for anything like this. I also want to stop the availability of pornagraphy to children and on TV and movies. It is poisoning the American family and society as a whole. Let us be the Christian example for families , putting God first and teaching our children purity for our world, Jesus is coming back soon,God will be pleased,Proverbs 22:6 Train up a child in the way he should go and when he is old, he will not depart from it. God will bless
