John Wood said this quote

...literacy is as vital as food, security, limiting population growth, and control of the environment.Education, after all, is the one issue that affects every other one. I think of it in the same way as dropping a pebble into a pond and getting a ripple effect. Educated people make more money and are more likely to escape poverty. Educated parents raise healthier children....The list goes on, just as ripples in a body of water emanate outward.
