My last comment on someone's post was agreeing that distillation was an amazing invention but yes, as you say, without purification we would be lost!
I have actually just started to donate money each month to a charity that spends the whole pound/dollar on water treatment in some of the poorest regions of the world because exactly as you say purification is so damn important and we take this fundamental for granted I think, thanks for reminding us all not to take the small things for granted. 😎👍
Indeed @stevenwood, its something we all take for granted. But no clean water, no life. End of story.
