“I asked the feedlot manager why they didn’t just spray
the liquefied manure on neighboring farms. The farmers
don’t want it, he explained. The nitrogen and phosphorous
levels are so high that spraying the crops could kill them.
He didn’t say that feedlot wastes also contain heavy
metals and hormone residues, persistent chemicals that
end up in waterways downstream, where scientists have
found fish and amphibians exhibiting abnormal sex
characteristics.”
