How did lewis hines work influence child labor laws

Lewis Hines had a large impact on reforming laws regarding child labor because he was a photographer and he would often photograph pictures of the hardships many families and children were going through during that time.

Kids at that time even worked in coal mines which are very, very dangerous and if I remember right, he was able to get a picture of the children at work, covered in black dust from the coal mines.

His pictures are shocking and once again, like I stated before, child labor is an ongoing problem in other countries.  Its very sad
