A map of swine feeding operations in Iowa, with a big concentration in the state’s northwest corner. From Christopher Jones’ presentation to the Iowa Academy of Science.
When it comes to manure, research engineer Christopher Jones of IIHR – Hydrosciences & Engineering at the University of Iowa has a knack for putting quantities and consequences in stark terms.
In blog posts earlier this year, Jones calculated how much animal waste Iowa’s millions of hogs, cattle, chickens and turkeys produce – an amount equivalent to 134 million humans – and where that puts us in the manure hierarchy of U.S. states.
The data caused a stir, with The Des Moines Register and other media playing up the implications. Now you can hear Jones discuss his findings in person.
March for Science Iowa is bringing Jones to West Des Moines’ Twisted Vine Brewery, 3320 Westown Parkway (just off Interstate Highway 235) on Wednesday, August 7, for a discussion over snacks (free), microbrew beer (on your own) and soft drinks. We’ll gather starting at 6:30 and begin the program at 7.
It’s one of two science-driven events worth your attention in the coming week.
