Rising Meat Consumption, Calorie Intake Complicate Efforts To Conserve Essential Phosphorus Resource

From the 21 January 2013 article at Medical News Today

Dietary changes since the early 1960s have fueled a sharp increase in the amount of mined phosphorus used to produce the food consumed by the average person over the course of a year, according to a new study led by researchers at McGill University.

Between 1961 and 2007, rising meat consumption and total calorie intake underpinned a 38% increase in the world’s per capita “phosphorus footprint,” the researchers conclude in a paper published online in Environmental Research Letters.

The findings underscore a significant challenge to efforts to sustainably manage the supply of mined phosphorus, a non-renewable resource widely used as fertilizer. When phosphorus is lost through agricultural runoff or sewage systems, it can pollute waterways downstream. In addition, because deposits are heavily concentrated in a few countries, global supplies and prices for the resource are vulnerable to geopolitical tensions…..
