Reel Earth Film Festival Presents a New Zealand premiere, an extraordinary documentary about Terra Preta, Toilets and Mars. It combines scientific facts, a bit of humor and fantastic animations.
Terra Preta is a fertile, water storing black soil that can be created out of all types of organic waste including our feces. Yes, feces, they're inevitable, and when we flush them away, we are wasting our waste while contaminating valuable drinking water.
In Undune, the knowledge about Terra Preta is discovered by Gregor: he wants to support the colonization of Mars and identifies the cycle of nutrients and water as the main challenge. Through conversations with Terra Preta pioneers and small experiments, he develops a system to make human feces and other organic material usable on a mars base. Gregors daydreams about an alien space explorer bring the perspective down to Earth, where Gregors dialog partners see the largest potential for Terra Preta. At the end, there remains just one question: Is there such a thing as useless shit?
An after-film discussion will be held by Dr. Marta Camps, Associate Professor Biochar & Soil Science Research at Massey.
