Subject: Why do the vegetable bags preserve the vegetables shelf life?

First I am trying to eat healthy.I purchase fruit and vegetables for home 
consumption.Sometimes the next morning the vegetables have gone from beautiful 
looking to molding wilted mess. I started investigating MY storage practises 
in order to prevent this.I did learn some should go in the fridge and some 
not,also storing together and not.I have found the GREEN storage bags have 
extended the life of my fresh fruit and vegs.AMAZINGLY>How does this work?
