There are numerous organizations in the world who work to reduce children mortality rates. Some of the biggest organizations are Doctors without Borders, WHO, UNICEF, and IFRC. All of the organizations work with children and adults. They help the children get healthcare they can't otherwise afford or even reach in their countries. They also help give money to the communities to build homes, get fresh water to the families, and also help in aid for food, schools, and other essential items needed for the families.
