Dietary shifts driving up phosphorus use

A new study led by McGill University researchers found that rising meat consumption and calorie intake have fueled a 38% increase in the world's per capita phosphorus footprint since the early 1960s. By reducing meat consumption, particularly beef, countries can significantly decrease demand for mined phosphorus.
