### Student Exploration

#### How can squares feed the world?

“The Square Foot Gardening Foundation is a non-profit 501(c)(3) entity whose purpose is to end world hunger by reaching out to families and teaching them how to grow healthy food for their daily meals, thus improving their diets and getting the family members interactive with each other. The Foundation teaches the original method of Square Foot Gardening created by our Founder, Mel Bartholomew, which uses less resources and requires very little work, yet produces a crop equal to a single row garden 5x\begin{align*}5x\end{align*} its size.” Read more: http://www.squarefootgardening.org/about-the-foundation#!__about-the-foundation/vstc99=page-1
