This is 100% true and pretty amazing how a single black reverend made the Ku Klux Klan’s leader change his mind on how he felt about black people.
Clean water is a huge problem. Probably way bigger than you’d actually think coming, most likely, from a nation in which it’s delivered in pipes straight to your apartment/house/building with no thought at all from you about how it got there or how clean it is. When millions of people get diarrhea a year and thousands die, it’s a serious problem. There is a new invention that Michael Pritchard talks about that is able to filter all water to give potable water from nearly any source at all. It filters out viruses, bacteria, waste, anything. Fantastic stuff. Absolutely brilliant.
