"Phosphorus is an element essential for all living beings and is thus critical in food production. Mined phosphate rock is a non-renewable global resource that is nowadays becoming increasingly scarce which poses a severe problem to the farming industry: it needs phosphorus in the form of fertilizers to sustain crop productivity.

Crops have two entries into the human food chain: direct consumption or indirect consumption by rearing animals which can be converted to human food. Different food types therefore require different amounts of phosphorus in their production. One kg of phosphorus can for example be used to either produce 3333 kg of starch roots (e.g. potatoes) or 16 kg of beef.

The loss of phosphorus to waterways, whether from agricultural fields through runoff or urban sewage through human excreta, can cause severe water quality degradation. This leads to eutrophication, harmful algal blooms, and impairment of our drinking water, recreational areas, and fisheries…"

Eat more beef, as a general category, but steak will work as well.

There are lots of other sources of fertilizer, and sea birds produce a significant amount of phosphorus in some locales.

Considering that a study of the Potomac River Basin found that the primary source of nutrients loading in the water were from the wildlife, more hunting would seem to be an option as well.

And venison is much healthier and requires no mined phosphates…
