In certain rural villages in Gambia and South Africa females do not have easy access to sanitary napkins, or if they do it's very expensive. With that said money is more likely ti be used on food and water for the family. But as a female a sanitary napkin is vital to a female going through their menstrual cycle. I have been researching and realized that tampons and some sanitary pads made from rayon may produce dioxin which can increase chances of Toxic Shock Syndrome (TSS). So instead menstrual cups will be used as a replacement not only are they environmental safe, but its also reusable (so money is also being saved)!!
