I'm setting off tomorrow on a 5 day canoeing trip. There was definitely  a lot of thought and planning around how to get potable water for drinking, cooking, cleaning up, etc. over the course of the trip for 15 people. It really makes you appreciate everyday access to clean water from the tap.

It's amazing how much of a difference clean drinking water makes. People take it for granted now, but it is such a basic thing, and not having it has to be an incredible burden.

So many people used to die from drinking dirty water. Now it is mostly a poverty issue as to why humans don’t have access to clean water
