Kimberly Gomes recently wrote an article on Biochar for the SF Chronicle exploring its’ potential to ameliorate the issue of nutrient loss in low carbon soil. Biochar is a substance we here at Lily Films have often mused about. In our short film, The Promise of Biochar we explore the substance (carbon made from burning biomass in low-oxygen situations through a process known as pyrolysis.)
It has been hailed as the perfect blend of indigenous wisdom and modern technology, and many claim it to be the silver bullet of climate change, soil exhaustion, and resource depletion. But can one substance really achieve all these goals without any externalities?
