Educating girls leads to better income, which leads to better economic growth for communities, cities, and nations. Better knowledge of nutrition, menstruation, mental and physical health education also leads to better health, fewer child pregnancies, and a longer life span for the girls and their families. Educated girls have healthier families and children. They are also much more likely to educate their own children. Educating girls is the greatest single thing that can be done to end poverty.
