Human bowels may hold key to greening the desert
Reducing greenhouse gas emissions, ensuring food security and fighting the spread of deserts are among the biggest challenges facing humanity. But the solution for all of them may literally lie inside humans – as we hope to show in this bog post -pardon – blog post. Human waste has traditionally been used in some parts of the Amazon to create Terra Preta – black soil rich in nutrients – the result of mixing charcoal and human faeces into otherwise less fertile soil.
This super-rich black soil captures carbon dioxide, stores amazing amounts of water and sticks around for hundreds of years. And, yes, it also works with other types of waste (watch our report about how this works in India). In short: Terra Preta may be a potential one-stop shop for creating sustainable habitats – even in outer space. A bunch of filmmakers thinks that the human colon may help colonize Mars or operate space stations in the future. Here’s the trailer for their complete Terra Preta sales pitch:
