What do our nation’s farms and chemical manufacturing labs have in common? Well, for some pig factory farms in America, more than you might expect.
Pigs poop—a lot. And when you concentrate huge numbers of pigs inside one building, you get a huge amount of poop. Yet collecting so much of that waste in one place and storing it there doesn’t just create foul odors—it can create fatal odors that, similar to the impact of chemical or biological accidents or weapons, can kill anyone exposed to them.
Instead of mustard gas, think of it more like manure pit gas.
