In Chapter 4 of 16, micro-philanthropist Adam Carter shares how his small, focused humanitarian project financing efforts complement work done by institutional non-governmental organizations (NGO). Carter highlights an instance in a Rio de Janeiro favela shanty town. A Dutch NGO purchases drums for a children's music class. Carter, noticing unmet demand, finances purchase of fifty new drums needed to increase class size by fifty students. The efforts shows how micro-philanthropic organizations such as Carter's Cause and Affect Foundation (http://www.causeandaffectfoundation.org/) serve those in need.
