We envision a food system that manages phosphorus more sustainably to provide abundant, nutritious food while protecting the health of rivers, lakes, and oceans.
We often say that food waste is phosphorus waste. If we want to realize a more circular economy for nutrients, we have to collect and process food waste to create composts, digestates and other materials that cycle back through the food production system. youtu.be/QoCDb58lTtc?...

That's a lot of phosphorus. Someday people won't believe we just dumped untreated manure into the environment, in the same way we now cringe at the thought of doing the same with human waste.
From Dr Chris Jones @theswinerepublic.bsky.social
"The waste produced by livestock [beef cattle, dairy cows, hogs, chickens & turkeys] in the St. Croix River watershed is equivalent to 3.25 million more people living in the region."
