in american universities there are biomedical engineering classes where they task american college students to formulate systems to reduce the amount of deaths caused by cholera in haiti because haiti is such a literal shithole that when they have earthquakes and floods the bacteria known as cholera - which, when it infects humans induces bacteria-laden vomiting and diarrhea - spreads from the shit to the water supply of haiti and casues a vicious shit cycle which dehydrates the population so severely that in one recorded case tens of thousands of haitians would vomit and shit themselves to death because they dont have access to working fucking toilets and gatorade.
