Can We End Hunger? My Trip to Uganda with The Hunger Project

I recently travelled to Uganda with The Hunger Project.

The idea was to observe how donators’ money is spent, and to speak with those on the ground who are making things happen.

My goal was not only to share their stories, but to do it in a fun and entertaining way (ie it’s NOT boring!)

I hope you enjoy my debut short-film, please let me know what you thought about it.

For the record, 5% of ad revenue on DietvsDisease.org is donated to help end world hunger through The Hunger Project.

So by reading this website, you’ve already supported the cause… thankyou!
