Human Waste To Help Global Fertilizer Shortages

Douglas McIntyre, Editor-in-Chief at Climate Crisis 24/7, explains that biochar made from human waste could help address global fertilizer shortages while reducing carbon emissions. Research shows that solids from human waste could supply 7% of global phosphorus needs, and adding nutrients from urine could increase phosphorus, nitrogen, and potassium contributions significantly. McIntyre notes the surprising fact that such a solution has only recently been studied.
